Error 500 InjectableFactory error after upgrade to version 8.0

Thanks for that. I have taken a look and an externsion from Eblasoft seems to be causing the issue. I will get in contact with them.

Try to find "Espo\Core\Utils\Layout" usage in *.php files of your instance. We don't have this class anymore. Maybe some customization still uses it.

Upgraded to 8.0.1 and now when you I go to an an entity, I get an error 500 message, some entities load, others dont. . The logs show the following..

DEBUG: API (0) InjectableFactory: Class "Espo\Core\Utils\Layout" does not exist; GET /Account/57cfce9f496001ce3;

I have re-applied permissions and done a command line hard rebuild but its still happening. Any ideas what may cause this? Many thanks
