If you haven't already, try clearing the cache and flushing all sessions (log out all users). Then test it in multiple browsers to see if it's still a problem.
Also, try with Dev. tools turned on in Chrome or Firefox (Ctrl-shift-i). Reload the page and check the console for JavaScript errors.
Hi
I cleared the cache logged out and in. checked the Devtools...nothing. The contexts just won't show up.

Here's a thought: Does the modx_context column in the DB have a 'name' field, and if so, is there anything in it?
What do you see when you right-click on the context in the tree and select "Edit Context"?
Yes you are right. The name filed is empty on both contexts. but how is that even possible?

That may come from making too big a jump when upgrading. It's important to upgrade to the major releases (the ones ending in .0) when upgrading. If you jump over one, you may miss database upgrades. The modContext table didn't used to have a name field. If you skipped the major release where that happened, you may have gotten the field later, but missed the code that copied the key into it.
I would have assumed that MODX would use the 'key' field if the 'name' field was empty, but maybe not.
