The problem centers around the editors filemanager. When you attempt to upload images to the server it craps out with an error "Connector is disabled. Please check the "editor/filemanager/connectors/php/config.php" file.
Some advanced users have posts on elaborate fixes for this -- but these fixes should be incorporated in a new release - if, indeed, they really work.
This problem has been going on for a month now and no solution has been posted in the forms by the staff.
I have users that need to use this function -- a lot. In the interest of serving my users I will be going to JCK 1.1.1 - I understand they do not have this problem.
It really is a shame. JoomlaFCK was a GREAT Joomla Editor. What happened -- I don't know. Maybe it was updates to Joomla from 1.0.13 to 1.0.15 - but whatever it is it appears to be affecting quite a few people and only silence from the staff in the forums.
If they ever figure it out and fix it I might be tempted to give it a go again as it WAS a great editor.
Within a few days of releasing version 2.5.1 on January 16th we released Critical Security update which causes a problem with the editor’s file manager.
Our response was swift because someone had posted a forum on the web that detailed how to hack Joomla! through the editor’s config.php file. So in being prudent we released version 2.5.1a within a few days. Some users reported a problem so we responded by released a fix in version 2.5.15 which resolved the issue.
If you update your 2.5.1 versions to 2.5.15 you will find that this has indeed been fixed. As configurations do vary occasional users may have problem but may I assure you of our on going efforts to resolves them.
