Can this software be installed on my site?
The in this thread announced version 184.108.40.206 is not installable because of the mentioned bug. A version with the fixes waits for a feature I am working on to be finished. I'll release a new version within the next few days, with or without a full implementation of the new feature (reporting of spammy or abusive entries to the forum operator team).
But you can install the stable release 2.4.20 if your hosting package or web server runs PHP with version 5.4 or newer and MySQL with version 5.0 or newer.
