Unable to login after migration - white screen

[Amanda1]

Hi

I migrated from PS 1.6.xx last night but have not been able to login the backend.

Do we still logon the same way?

On the front end both of my stores have the maintenance screen

 

Many thanks

Hm I checked the url and understand now, that you don't even see the login page. I thought you will get a white screen after you try to login.

Maybe this thread from ps forum can help you: https://www.prestashop.com/forums/topic/592769-admin-login-blank-page/

White page means a substantial problem, like a PHP syntax error. Time to look up the server's error log, if available.

If your hoster doesn't provide an error log (ridiculous, but some actually do not), move overrides and non-thirty-bees-modules aside:

- Using FTP, find all pages with .php suffix in overrides/, which are not index.php, and rename them to ....php.off.

- Create a folder "modules.off" at the root of the filesystem.

- Move all modules not from thirty bees out of modules/ into modules.off/. In doubt, move more of them, a shop basically works without any modules.

- Delete cache/class_index.php. thirty bees will regenerate it.
