Nigel is on Vacation. This is Minesh here and I'll take care of this ticket. Hope this is OK.
Can you please try to delete all Toolset plugins using FTP and check if you able to get your site working? If yes:
- Then please try to install Toolset plugins one by one.
Since CRED Frontend Editor update broke the site I deleted it altogether. The site came back up. I took this as an opportunity to perform other critical admin tasks prior to updating each Toolset plugin, which I have yet to do. Regarding the editor... is it required, AND what exactly is it useful for?
After your answer, I'll update Toolset plugs one by one.
I determined that the CRED Front End Editor aka Toolset Forms was an older version pre-Toolset Forms. Deleting original CRED Front End Editor folder via FTP opened up admin access. This allowed me to perform other admin tasks. Afterward, I uploaded the CRED Front End Editor zip file to cPanel, then extracted it into a newly created folder in plugins folder. I then updated plugins as admin one by one (in this order) Types, Views, Access, Commerce, etc. Activated Toolset Forms and ... Eureka!!! Back in business!
