I redesigned my site with a theme based on Typhoon - so Tailwind and Alpine. To upload the changes to the server I first upgraded GRAV and plugins, then added the new theme & the missing plugins, changed from the old theme to the new one and lastly deleted and re-uploaded the pages folder.
Everything seems to be working fine from the front-end but when I go to edit a page on the admin side I get:
Server Error
Sorry, something went terribly wrong!
0 - An exception has been thrown during the rendering of a template ("Invalid argument supplied for foreach()").
For further details please review your logs/ folder, or enable displaying of errors in your system configuration.
I've checked everything I can think of - the licences are there, the system and plugins are all updated, dev and prod are both on php 7.4, I've emptied the cache...
The grav log says: An exception has been thrown during the rendering of a template ("Invalid argument supplied for foreach()"). which we already knew...
This is the verbose version:
