Hello,
I am having some issues with Visual Composer. I deleted the old and purchased and installed the latest Version on Thursday, and I could only open the elements box, but not see any elements to add.  I tried adjusting all settings with no luck getting them to show.
The bigger problem I am having is when I have the plugin active, some pages on my site will not load. Specifically any pages that are accessed by going to the drop down sections in the navigation menu (ie. Properties-resales or our projects-tolland forest). With the plugin active, I actually can not even see the drop down arrows for the menu. I find that when I deactivate the plug in I can get to those pages, but they are displayed in code only. If you could please help me with this I would appreciate it very much. In the past I have had no issues with Visual Composer (other than an update required) and use it on multiple sites I have with Word Press.
