Hello !Friendica Support
my timelineS do not load anymore, either they do not load entirely or just some posts are loaded and then it stops. This happens since yesterday, I did a git pull before from stable, but I think there were no changes.

There is nothing in the PHP Errorlog when I refresh /network, but there is this in the #Friendica log for a grep for "Error" during the time of the reload.

I can also not post from at least @utzer, I get an HTTP 500 error.

It is the same for @Admin (of friendica.utzer.de), both accounts have this problem, on both I did a git pull. 😕

Looking forward to any help or tips how to trouble shoot the problem.
