Hello,

I cannot open the forms extension on my dev env. I have tried everything (full db synch, all models build , etc).
I checked on another machine and it opens without any problem.

What could be the cause of this error?

Please give us some context. Is it related to a single extension only? Did it work before? If so, does it still work if you take a version of the file from the time when it worked?

Hello Martin,

Yes, it is only related to this extension and did not happen before. I have already tried removing the file from this specific location. After downloading the latest version from the repository, the problem still exists..

I deleted the existing extension and created a new one from scratch.
