Hi,
I just upgraded to 2.9.1, the site is working without any problems but I am having problems setting the themes I installed.
After installing themes or widgets, I got a completed message but none of the themes or widgets are available to use.

Is there a permission I need to set?

Thanks

Update:

I managed to use the new themes after logging out and logging in again.
I still cannot use the new widgets (File System Management)
