Visual Editor Causes Previously Posted Text to Disappear

Have you tried:

– deactivating all plugins to see if this resolves the problem? If this works, re-activate the plugins one by one until you find the problematic plugin(s).

– switching to the Twenty Ten theme to rule out any theme-specific problems?

– resetting the plugins folder by FTP or phpMyAdmin? Sometimes, an apparently inactive plugin can still cause problems.

– increasing the memory available to PHP?

I’m using the Twenty Ten theme, so I will try the other ideas. Thank you very much! Donna
