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?

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

    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..

    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?
