I’ve resolved my issue by turning off all my other plugins. Once the Advanced Access Manager was the only plugin running it began working again. I turned on plugins one at a time until AAM stopped working. My culprit is a plugin for a custom dashboard.
It might be worthwhile to turn off all your other plugins and see if any might be conflicting with AAM.
I’m having the same issue. Everything was working great until yesterday and now the plugin stalls and I can’t change between current roles to change settings. I’ve uninstalled and reinstalled but it didn’t help the issue. Before it started stalling, the plugin was great.
