I just got the same problem. Oddly I can generate reports but I cannot customize. The "Manage report templates" are all empty in all tabs
These were all populated earlier today.
I tried the "Reload all global reports and templates from disk" button but it did nothing. I tried fooling around with the custom report library folder just in case. I exited ReadyAPI and restarted it. I also rebooted my machine (a virtual machine). But still no global reports and templates...
I even tried uninstall and then re downloaded the ReadyAPI 2.2.0 from the SmartBear website and reinstall ReadyAPI 2.2.0. Same deal. Incidentally I was able to successfully create a custom report for the test suite. I can run it. So ReadyAPI acknowledges the reports folders. It just won't let me customize anymore!
I can see the reports and templates when I run ReadyAPI as root but not user. So I'm not sure of what permission settings I need on what files / folders to allow me to customize templates again once I log in as user.
