Hi,

I tried updating umbraco forms to version 4.4.0 and all of the forms on my site stopped working. Then I tried to uninstall the new forms plugin so I could revert and try again, however, now I cannot get into the back office and my entire site is down. I get this error message:

At this point I am completely lost and I would greatly appreciate it if someone could help point me in the right direction to get this issue resolved.

Thanks, Derek
