Problem: The issue here is that the user is getting an error 500 when activating our access plugin.
In this user's case the error was being caused by another plugin, so the recommendation was for them to disable all the non-toolset plugins and then activate access then being activating the other plugins one by one.
This is the technical support forum for Toolset - a suite of plugins for developing WordPress sites without writing PHP.
