I just upgraded to PHP5.3 and am getting the following:
warning: Invalid argument supplied for foreach() in .../sites/all/modules/wysiwyg_filter/wysiwyg_filter.inc on line 523.
The line number changes depending upon the node I'm on, sometimes I also get:
warning: Invalid argument supplied for foreach() in .../sites/all/modules/wysiwyg_filter/wysiwyg_filter.pages.inc on line 425.
Anybody know if this is easy to fix? I looked through the code, and it looks like it's not getting a variable correctly from the database. I can see if I can dig up more details...
