Hi there,
I am using Shaper Saloon Template here:
https://www.derfriseur-korbach.de/
I tried to update SPP3 to SPP5 but I cannot acces the backend editor any more then. I get following error:
I had to install a backup. Frontend Editor was working - but buggy problems - site in Frontend appeared. Admin without any errors.
What can I do to avoid this when I try to update once again?
