Hi Guys,

When i Click on "Watched Forum" function in my account preferences (personal details), i got this error message:

An exception occurred: Invalid argument supplied for foreach() in <path>/library/XenForo/ViewPublic/Watched/Forums.php on line 21

1. XenForo_Application::handlePhpError() in XenForo/ViewPublic/Watched/Forums.php at line 21
2. XenForo_ViewPublic_Watched_Forums->renderHtml() in XenForo/ViewRenderer/Abstract.php at line 227

5. XenForo_FrontController->renderView() in XenForo/FrontController.php at line 158
6. XenForo_FrontController->run() in <path>/index.php at line 13

Anyone know why this error happened?

Thanks!

It is triggered by an outdated add-on, though I'm not 100% which one it is.
