Duplicate Server error 553


Active member

I wanted to post pictures in a new thread, and then - when I tried to edit it and delete a picture in it - for some reason I got the Server error 553. Now I cannot create any new thread in this particular forum, always getting this message:

array_fill(): Number of elements must be positive
  1. XenForo_Application::handlePhpError()
  2. array_fill() in XenForo/ControllerPublic/Forum.php at line 553
  3. XenForo_ControllerPublic_Forum->actionCreateThread() in XenForo/FrontController.php at line 347
  4. XenForo_FrontController->dispatch() in XenForo/FrontController.php at line 134
  5. XenForo_FrontController->run() in /(...)/xenforo/index.php at line 13
Any idea for a solution?
