Blank page in manager after editing document or settings

Hello ,

I have a problem with modx 2.0.8 (and I’ve got the same issue in 2.1 RC) when I try to edit a document or a setting. I have a blank page instead of the manager.
The only way I found to resolve my problem was updating the modx. Then the manager come back for a while but it crash again. But the frontend is still accessible.

I just do basic action, like creating a document, changing my website name or activating friendly urls.

I developed many website with modx, and I never had this problem before. I also have other sites wich use modx 2.0.8 and they work perfectly. I hope you can help me!

Config :
- Apache server
- PHP 5.2.17
- MySQL 5.0.32
- Modx 2.0.8pl trad. (2.1 RC)

Thanks,

(Sorry for my english)

I’ve had this problem before and it can be caused for some different reasons. First of all, upgrade TinyMCE to last version.
Then, try disabling you plugins, that could be the reason of this problem.
