When downloading a file (any file) I get the above error.
The problem is solved by disabling "Activate log function for Downloads" (but that can not be a good solution ;) )
I Tried making the log_ip-field bigger (VARCHAR 250 instead of 25 just to be sure) and that also did the trick (might be a better solution) ...
This is a new Joomla! 4.2.5 installation with jDownloads Version 4.0 pre beta PHP version 8.0
Hi Yves,
thanks for your bug report. I will change this with next pre-beta 4.
