After few days, usually 1-3 days, the "Content - !JoomlaComment" plugin (4.0.0 februrary 2008 Daniel Dimitrov) becomes unpublished by itself!!!
The only user that enters admin is a Manager level user without access to unpublish the plugin. No user except me (that I do not enter the admin side at all) has access to unpublish plugins. The system was live without the problem for more than 6 months. The behaviour started after the 20st of September 2010 and I cannot find out what is going on.
Do you have an idea of what is causing this???
