Save buttons keep loading with and getting error 500

[Steve]

I almost always get it when I'm at Catalog > Products adding/editing products.

Found this thread: https://stackoverflow.com/questions/34726844/prestashop-endless-spinning-product-save-button but I'm not sure if I should try the solutions posted there? (I already tried using another browser) I'm on localhost.

Does anyone know how I could fix this?

Tab : Attachments (500 Internal Server Error) A server error occurred while loading the tabs: some tabs could not be loaded. Please try again by refreshing the page. If you are still encountering this problem, please check your server logs or contact your hosting provider for assistance.

Are you using thirtybees or prestashop still? Those problems were fixed a while ago in PS, so thritybees should also be ok

Do you have any installed modules that add tabs to the product page in the backoffice?

@haylau

Do you have any installed modules that add tabs to the product page in the backoffice?

Yes, Product Arrangement and Restrict Access. I think it started when I installed Restrict Access.

Also please note that I'm using PHP 5.6, I have had some memory problems so I'm currently trying to upgrade to PHP 7.

[haylau]

Disable those modules and see if the problem is still there. If the problem goes away, enable ONE module and test again, then switch them about. You should then be able to tell if the module is at fault

Was the problem just after switching to PHP7? Many modules are not compliant

I still haven't switched, so no. I'm trying to do that but I'm not sure how to do that without ruining my databases.

@steve change php version will not ruining your database, if you not sure just backup your database and change it to newer php :)

Can I reinstall XAMPP?

Or should I do it manually by dwnloading PHP? Because that isn't working for me.

[dosbiner]

I never tried xampp, I think you can upgrade php version without reinstall it. or you can do full backup all your files and database, and then reinstall xampp.

I just went to PHP 7.3 and my pages are now blank when I navigate to the shop. I replaced htdocs and mysql with from my old site.
