HTTP 500 error for /administrator/index.php?option=com_community
I tried it again (with different users and different browsers) but it is still not working for me.
In the meantime I tried also some other things. I took a copy of the site and ran it in an local environment. Also here the JomSocial backend was not working. Then I updated to JomSocial 4.2.6 and it is working since (at least most of it). The Member Locations map is not working right now. I will probably update the live site within the next days too.
If I still have issues after that, I will let you know.
