New thing popped up this January. My postmaster has a limit of 30 seconds for a script or it cancels it. The problem is that the script appears to just keep running and eventually overloads the server's RAM and crashes the system. The offending script is amr-ical-events-list/includes/amr-rrule.php
We get various points within the script that causes the problem. Line 761, 52, 51, 964, 1028, and 55 have been identified. I am using PHP 5.2.17.
Also, I recently I can no longer put a URL in the widget's "Calendar URL" as it now shows up as the HTML itself in the widget on my page.
