User detail/edit view returns a blank page

I installed a couple of plugins last week (enhanced security suite) and now when I try and view, or eidt, a user I only see a blank screen.

Any suggestions as to how to diagnose/fix this?

you should have a look at the common log files, but in the end, you can also ask the author of the store-addon for assistance (each plugin has its own support section, e.g. here).

Update: It turns out it’s the Outlook Plugin (from Sales Agility) causing the issues, once uninstalled everything works fine.
Luckily I have a call with SA later today :slight_smile:
