Always get 'data may not be saved' warning 3.5.1

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 default 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.

I tried all three.
-only 2 plugins are Akismet and Hello Dolly and both are disabled.
-same result with twenty twelve
-reset plugins folder by renaming the plugin folder (am running WP on my own computer (Fedora 17).

None helps.

You could have a damaged database. Or the issue may be server related.

It’s happening again on a totally different site hosted in a totally different location.

Interestingly, it doesn’t seem to happen when I type in a post, but seems to happen consistently when I have pasted in a bit of .rtf copied out of LibreOffice Writer. It doesn’t seem to happen if I “sanitize” the rtf by running it through gedit first.

This seems to be a new problem–I haven’t had trouble, that I know of, pasting from .rtf in previous versions of WP.

Thanks.

Stop pasting content in from other applications. It can cause all kinds of problems because it can contain “invisible” formatting characters.

Hmm. Hasn’t been my experience in the past, but maybe something made the latest version of WP a bit more sensitive.

I just discovered the “Paste from Word” button. This seems to do the job for me.

Thanks.
