Thanks again P_I. It looks like all of the necessary permissions are there.
Something else I noticed, after disabling and re-enabling some things, the Extensions category is enabled and located under Customise, but thee is now an Extension Management category located at the bottom of the Module Management list that I am unable to move under any other parent directory. Is this normal?
I'm wondering if the whole extension management set of modules is irreparably screwed up and if I am able to completely uninstall them and reinstall them. Is that possible?
Thanks so much for your assistance!
