Hi Jean-Marc Burri,
For sure we will assist you about this issue
After a while troubleshoot this issue, seems like I've hit the error below:
<b>Warning</b>: require_once(/home/jmmbch/public_html/crcs.ch/administrator/components/com_easysocial/includes/storage//.php): failed to open stream: No such file or directory in <b>/home/jmmbch/public_html/crcs.ch/administrator/components/com_easysocial/includes/storage/storage.php</b> on line <b>26</b><br />
<br />
<b>Fatal error</b>: require_once(): Failed opening required '/home/jmmbch/public_html/crcs.ch/administrator/components/com_easysocial/includes/storage//.php' (include_path='.') in <b>/home/jmmbch/public_html/crcs.ch/administrator/components/com_easysocial/includes/storage/storage.php</b> on line <b>26</b><br
Seems like some of the files is missing. Can I have a permission to re-install your EasySocial to the latest?
Apart from that, the FTP access you've given above, I cannot get into /administrator , /components etc directories
p/s: re-installation process will effected the customization in the EasySocial core file, if you make any customization in core file (EasySocial) you're suggested to make a backup beforehand
