I have been experiencing problems when I try to post new or change existing posts. When I use IE 9 I cannot click into the posting box, change font color, justify, etc. When I use Firefox I can write and publish a post but the font colors do not always change and I experience other formating issues.
I've tried to fix by:
- 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.
- re-uploading the wp-admin and wp-includes folders from a fresh download of WordPress.
None of these worked for a fix. Please advise on how to correct these issues. Thank you!
