I tracked a problem I have been having down to the JoomSEF plugin on my system. With the plugin enabled in the extension manager when a back end user hits "SAVE" on an article you get a white screen and the article saves but remains locked. If I disable the JoomSEF plugin then the SAVE button works fine and I am returned to the article to continue editing.

However, even with the JoomSEF plugin turned on the SAVE AND CLOSE button works fine and does not lock the article. The white screen and locked article problem only happens when JoomSEF's plugin is enabled. I am not talking about the enable switch in the JoomSEF control panel I am referring to the one in the main Joomla extension manager.

I also moved the JoomSEF plugin around in the execution order to check and it still white screens no matter where JoomSEF's plugin is ordered at.

Any idea what is going on here? I am running Joomla 3.4.1 and JoomSEF 4.6.2

Anyone have any insight on this problem? Or any idea how it might be solved?
