How can I restore my admin login?  surely prestashop can't go so wrong from merely upgrading modules (these were all stats modules in the first 10 listed in Module Manager )

Did you try to clear the shop cache using FTP manually?

This often resolves such issues after module updates.

You can delete the contents of the var/cache/prod and var/cache/dev directories to clear the cache.

[ZHSoft]

Enter the control panel and delete all files under var/cache/prod and var/cache/dev.

Thanks for the suggestions and I am sure that's what the issue is.

I decided to do this in the cPanel under the file manager.  But the files showing there are not not those of my current Prestashop installation.  They are from a previous installation as I can see by the admin directory having a different name. The file manager shows my admin directory as admin1904 but my current directory as you can see from the error messages is admin256zkv3bw.  

I shall go back to my hosting company and see if i can get access to the right files.

Many thanks, i will update here once I have cleared var/cache/prod and var/cache/dev

[tamarillojohn61]

Are you sure I should clear all of var/cache/prod?  There are a heap of folders and files there.

Alright, problem is fixed.  Thanks heaps for your accurate and prompt advice. You guys are legends
