I have discovered that if you activate the TinyMCE Plugin and set TinyMCE as the default editor in Global settings you can’t add or edit posts.
The subject line can be written in but the main body, although visible, cannot be typed in. path: P appears bottom right which I don’t recall seeing before.
When trying to edit a post, the post appears very briefly in the edit window and then the window goes blank.
To get back to normal I have to switch to test in global settings and de-activate then re-activate the plugin, making sure that use TinyMCE is not set in global settings.
Then the first post after this switching around is prefilled with <p><br data-mce-bogus=”1″></p>
Not sure if this is specific to my set up and I’m sure it hasn’t always been the case.
Edit: Just realised that, although I can activate the post window I can’t actually post with the TinyMCE plugin enabled at all. Text editor is OK
