Thank you for offering these suggestions, but I think I can take it from here.
It seems that no matter WHAT plugin combination I tried, I only had a limit of 18 plugins able to be activated at once, including user role editor pro, before my VC grid builder stopped working.
This leads me to believe that there is simply excess data or junk in my build that is causing the wordpress “heartbeat” function to overload with ajax calls. I installed the “WP Sweep” plugin to clean out some of the orphaned data and this seemed to help. I have now activated 2 additional plugins and it still seems to work.
This could also be the case that I don’t have enough memory allocated for my WordPress build?
I’m not too sure, but it sounds like the cuplrit is more technical, and not related to your plugin at the moment.
Thank you again for all your help and suggestions!
