Managers Right Side Comes up Blank

For some strange reason the right side of the manager (2.0.8. )
comes up blank. All the trees and menus are working OK but when
something is clicked in either one, nothing show in the right panel.

The site works perfect.

Any pointers?

Environ:
MODX 2.0.8 (latest) - Traditional
Linux-CentOS: 2.6.18-164.el5PAE (kernel)
PHP: 5.2.6
MySQL: 4.1.22-standard
Apache: 1.3.41
Browser: FF 4 and Opera 11

Did you do anything before this happened (upgrade, new site)?

Try manually deleting the files in the core/cache directory, if you haven’t already.

You could also upgrade to 2.1 (although it’s still an RC version) which has improved caching.

Bob, you are a genius!

It mostly works now after clearing the cache.
The only thing that was done was to change some
server permissions... maybe that did it.

The only problem remaining is that when trying to
access the Packages it indicates that the assets dir and
the components dirs do not exist... maybe because of the
permissions...

I will upgrade to 2.1 to see if that fixes it... I wanted
to wait until 2.1-pl, but I will do it on Monday. (This
week we have holidays over here...)

Thanks again...
