So, people are having problems with posting to WordPress since the Tiny MCE update. These people include my writing partner. The problems include, but are not limited to: Flipping between Rich Text and HTML doesn't work, Saving doesn't work, Links within the edit page open up in full view instead of loading in innerHTML, Images in the image-window aren't loading or will not upload, etc etc. All in all: posting is a gruesome, time-consuming task.
All posts with questions on this matter in the forum have been marked with "resolved".
What's been resolved? "Check your firewall, delete your cookies and cache"?
No. Doesn't help.
The only thing to change with my writing partner's computer/browser setup is the code on WordPress. It's seriously a problem you should look into having fixed asap, or do a full rollback, because the problems aren't fixable on the user-end.
Being backed up on support on a free-for-all service is perfectly fine, but pretending to fix things and saying you're done is not.
Do over.
