First, don't expect a developer to have any supernatural powers, a seventh sense ... whatever.
Thus, if your report just looks like "My community appears to be corrupted all of a sudden", the core team is as clueless as you are. And without any background nobody will be able to help you.
So, with every error report we need at least:
- some useful information or a screenshot which may help us getting an idea what's going wrong
- the URL of your site
System Info component ( https://www.opensource-socialnetwork.org/component/view/1963/system-info ) being installed and enabled
Finally, please report different problems separately. Open a new thread for each single issue.
