Missing Contexts Listing in Revo

My MODx site works just fine. I am now experimenting for the first time to add another context for multiple site administration. When I go to Menu > System > Contexts nothing is listed. It’s empty. When I attempt to add a context it saves but is not added to the list nor on my Resource browser window. I checked the database modx_context table and it does show mgr and web contexts. I could manually add this in the database but I would prefer to have it fixed so I can work with it through the Manager. Any suggestions?

flush permissions/clear cache might work.

Thanks for the suggestions. I tried clearing cache and flushing permissions. Same problem. I see no Context keys listed and I’m unable to add any new Contexts.

SO it appears that I am not able to edit Contexts in general. Even the default web context. I receive no errors just the changes do not apply or if I click "edit context" the edit window just infinitely clocks.

Any javascript errors?

Try re-running setup/ in upgrade mode.

Thanks for the replies. I actually saw that I needed to upgrade as I was running 2.0.0. I know have 2.0.3 and can view my contexts and edit them now...and the upgrade was nice and smooth. MODx is awesome!
