Hey @emwhy,
Please don’t get us wrong. We want to help. But, your issue is coming from a third party plugin and not just one but two (AdRotate and W3 Total Cache). The issue could be caching. It’s hard to tell if there are several variables at play like my colleague have said previously. If let’s say the issue is only with AdRotate and Cornerstone only, we could login and check if the issue is coming from Cornerstone. But even with that, we could not promise an immediate fix if the issue is coming from Cornerstone. That is due to the fact that our development team could not account all the potential variables.
If you could setup a staging site with AdRotate and Cornerstone only and document the problem, we could login and see if Cornerstone is causing the issue.
I hope you understand.
