Quote from: Chen Zhen on September 15, 2020, 07:40:52 PMThe maxredirect=10 is something I tried a few days ago and it is already removed.
I don't see anything else related to the arcade
The upload script works on 2 local test forums (SMF 2.1 & SMF 2.0).
It works here on this forum (SMF 2.1) and I just tested it on doc skhills (smf 2.0).
All of them are using RC7 for the latest arcade version.
Imo something is not right with your Apache settings.
Also note that having a test forum in a child directory of that forum will cause cookie problems for both forums.
I've been through that myself.

Try to see if there are errors from the arcade files within the last day.
Any error messages there might give us a clue as to what is causing the upload script to fail.
