Last week I installed Graphene on a BlueHost server that had recently transitioned to PHP 5.4. I had no noticeable problems with the install at the time. However, today I am having problems expanding the options menus. I click on the little arrows, and they don't want to expand. The arrows display by default even without a mouse pointer over them, and all of them point up rather than down.
I have another site on BlueHost using the Graphene theme that behaves normally. However, I am not certain if they have switched that server to PHP 5.4 yet. Could there be a PHP compatibility issue here? Am I overlooking some other potential cause for this problem? And is there a solution?
