Hi,
Unfortunately, I have to raise this issue again.
Last Tuesday I tried to lift the page to Joolma 4 but it crashed.
The website has been restored as before without any problems.
We had previously gone to Joomla 3.10.2 and JomSocial 4.8 but I was a little surprised when I checked the Joomla Pre-Update Check and saw that it warned that there would be a problem with "System - JomSocial System - Plugin" and that was the only warning.
If I disable the file, the website will not work.
Although the file is version 4.8, it is dated July 2011.
Should that really be the case or what could be the problem?
Regards
