Is that so? The error shows on the get go, even if you try to enter the platform, the main page, I mean?
Because in my case, it seems it's showing everything without the error. But it may due to the geo..
The error appears for logged in users. If you try accessing it as a guest or in logged out state, the homepage works fine.
The homepage sometimes works fine in logged out state. I tried with several VPNs no cokies no cache and it worked one time out of 10 from a French IP all other from FR, USA and GB were error 500 even the homepage logged out.
The only thing that works is blocking for German or Dutch IPs.
I just hope nobody won't get put into the sink because of this, as it was said - we don't want the end to be near for the project, because it may seem like a sign of it.
