Please contact the administrators and inform them of the time the error occurred, and anything you might have done that may have caused the error.
It seems it works fine now. Yesterday we had global problems with PHP on server, they were not related to your plugin. Maybe after fixing them your plugin began to work too. Anyway thanks for your great help..
