File does not exist on system: cache/themes/SuiteP/modules/SecurityGroups/Popup.tpl

I have Version 7.11.15. When I click on Admin / User Management / and then click on Select in the Groups sub panel I get the following message:
File does not exist on system: cache/themes/SuiteP/modules/SecurityGroups/Popup.tpl

I have tried repairing the system but nothing changes. I can’t to seem to find a file named Popup.tpl anywhere in the system.

Have I lost/deleted a folder? I installed a completely new version in another folder and don’t find this file in a freshly unzipped Suite CRM.

Any idea?
