Thank you! One more step fixed. Really appreciated.

Yup.

Migration module psonesix. Been having issue throughout with it. I did a manual upgrade and that failed as well, in the end, despite getting me the closest results to my PS store, because apparently the database have changed. I have not touched the core but there are several overrides because of modules. However, I disabled all third party modules and overrides before attempting migration. Right now I am starting over with a backup that I have to reinstall and will attempt a clean migration from a fresh PS 1.6.17 install.

I did try on a dev site. At some point, I need to migrate my live site... Things that work on dev site do not work on live site and vice versa... This has not been a pleasant or easy ordeal so far... I will try what you mentioned. That file was not there.

No, there is not as that directory does not even exist. I think it is being called by the migration module. The location of the CryptBlowfish file is in home/php/Crypt/

The Pear package for CryptBlowfish is also installed...

I went back to an older backup and reinstall everything. When I try to upgrade using the TB migration tool, I get this error when updating the database: Error [Ajax / Server Error for action upgradeDb] textStatus: "error " errorThrown:"Internal Server Error " jqXHR: " " The PHP error log gives me the following error: PHP Fatal error: Class ‘CryptBlowfish’ not found in /home/public_html/classes/ However, mcrypt is installed and enabled... The end result is that the database does not install properly. In some cases, I get a 500 error and can no longer log in.

mcrypt is installed and working after checking phpinfo. Not sure what is wrong but it is what apparently prevents the database from updating properly.

I get the following error when updating the database: PHP Fatal error: Class 'CryptBlowfish' not found in /home/public_html/classes/

Will do. Thanks for the pointers.

AAAAAARGH!

Using the migration module did not work properly (PS 1.6.17). Most of the modules did not work, theme was broken. What I did is do a clean install of TB, reinstalled the theme from TB, installed all modules from TB, then imported the PS database into the TB database. That is the only thing that led to my site looking remotely like it used to be. But there are a few issues with some modules, the categories problem and some functions suddenly missing from TB. Why would that cause issues if the core files are more or less similar?

After three days of painful transfers, I have finally managed to get my shop somewhat back on its feet following a migration that is not easy by any stretch of the imagination. I have had help from Petr from Datakick and he has eased the process somewhat. Now I cannot modify anything in Categories. The only way for me to do anything there is to go inside the Database and edit it there. Nothing works on the backend. I get the following errors: Failed to update the Status or An error occurred while updating an object. category () Any idea how to fix this? Also having vexing problems with the file manager calling scripts through http instead of https, basically rendering the search engine unusable as everything gets blocked by the browser. It used to work fine under PS. Several modules worked when I did my test site but ever since I have uploaded my backup from the database, a few of them have ceased working. Also, some functionalities of TB have disappeared such as the possibility to put custom codes or the duplicate content checker. Any ideas why? Thanks!!!

There is nothing seemingly specific to this error or even the timeframe of the migration in the error log. I will attempt to manually upgrade.

Still waiting for the host to allow us access back in...

I have attempted a migration of our site. Things were going fine until the migration module attempted to update the database. The following error appeared: [Ajax / Server Error for action upgradeDb] textStatus: "error " errorThrown:"Internal Server Error " jqXHR: " " We also ended up being locked out of our own server as I assume it was interpreted as a hack attempt - our IP got blocked. I have been looking online and it appears to be a frequent error with older versions of Prestashop, although there does not appear to be a consensus on a solution. Anybody has any idea? Should there be protection disabled server side to allow for a smoother process? Not too keen on having the server exposed but not sure on how to proceed. Any help would be appreciated.

@datakick has kindly offered to help - so I started with 4 problematic modules, two of which worked seamlessly on his end but not on mine - and he has spent several hours on the issue so far, to the point that I am actually feeling bad about it... However, it appears I was not totally crazy. When I test things, I try to minimize variables as much as I can and I had removed the other profiles besides superadmin while I was trying to test the compatibility of all the modules we use in our normal day to day in our PS shop. Here is @datakick assessment: "I’ve found a bug in core code that prevents creating new tabs in back office. This bug manifests only when there is just one permission profile in the system - superadmin. By default, 30bz has 4 profiles (superadmin, translator, logistician, salesman), and that’s probably the reason why nobody haven’t noticed this bug yet. You have probably removed these profiles when you installed 30bz, right? Anyway, this bug prevented installation of almost all modules, respective it may have terminated installation in-the-middle of the process. Some modules may have been registered as installed, but in fact they weren’t. After I’ve fixed this Tab bug, I’ve managed to install the first two modules you send me without any problems. The other two have some override conflicts. In fact, it’s not even possible to uninstall them at the moment. Possibly another bug in the core." So there you have it. I am still testing several modules that we need - I shall keep you guys updated.

Thank you!

I am definitely up for modifications, even if it to help us inch closer to something that works. Here are the links to the faulty modules: Stock Editor: https://addons.prestashop.com/en/fast-mass-updates/21726-stock-editor.html Multicurrency: https://addons.prestashop.com/en/price-management/19253-multi-currencies-for-products-in-backoffice.html We use both everyday in the shop, so it is a big hurdle in terms of migration for us. Besides that, I have been testing extensively TB and I like what I see. It is also very reassuring to have such a reactive forum for help. Let's just say I have not been used to that with Prestashop. I appreciate everyone's input and willingness to help.

Awesome idea! Thanks for sharing it!

Forgive my ignorance but informations.tpl is located where?

I wiped everything and did a clean install of TB 1.0.4. A lot of the problematic modules still give the "The following module(s) could not be installed properly:" yet they install and appear to be functioning fine (although not tested in depth). However, two remain problematic and will not install period. Stock Editor and Multi currency for products in backoffice.

I think I have figured out the issue with Prestablog - it appears to be a conflict with another folder named the same way by another blog module. So at least one to scratch off the list.

@datakick It is the same environment and the same server. I try to not introduce too many variables. We used the same database version (MariaDB) and the only difference as far as I can see is that the prefi is tb_ instead of ps_ - everything is the same version, InnoDB, etc. PHP is 5.6 for all the installs - both prestashop and TB - planning on eventually get to 7 but we had issues with prestashop 1.6.17 using 7 so we had to revert to 5.6. I am not honestly 100% sure about what is causing the issues - all I know is that all these modules work in PS 1.6.17 but installing them on TB causes some of them to no longer work or not even install. I will look at overrides to see if it is an issue, like suggested above. But if you want to have a look, I will be most grateful. I will contact you shortly. I did switch off the 'disable non TB modules'. :) @Baarssen: When I installed Prestablog, I got the message that it could NOT be installed, yet bizarrely it did. It does look functional and I plan on testing it further but I am worried because of that message. I deleted it and reinstalled it several times and I always get the message: This module could not be properly installed. I want to thank everyone for their quick answers - it is very much appreciated.

Valid points Baarssen. It just gets overwhelming when a site with over 20,000 products is on the verge of losing support with the Prestashop move and seeing stuff we invested lots of money in apparently becoming suddenly useless is not a lot of fun... Here is a list of the modules that appear to no longer work in our case: Stock Editor Gift Card (not the prestashop version, the advanced module) Advanced Invoices Hard Currency for Backoffice (allow control of various currencies through categories - also handles mass discounts) Prestablog Card Payment Employee Access (we need that as we use it for third party vendors who want to only be notified of their sales and manage their products) YouTube Carousel Facebook Social I have not finished testing some of the others that look questionable. I will update as I hit road blocks.
