Using the latest version of TinyMCE Advanced and WordPress, I can no longer update old posts.
If I do try to add some new text to an older post, when I press the UPDATE button, all appears to be fine: the TinyMCE visual editor window refreshes and looks good.
But when I visit my website - by either using the VIEW POST button or by entering the URL into Firefox - the post is EMPTY! The Headline is there and the comments are there, but nothing in between.
I disabled my 14 plugins and re-enabled a few of them one at a time in this order: Skimlinks, Askimet, WP Super Cache, FeedburnerFeedsmith, wp-jquery-lightbox, TinyMCE Advanced.
After enabling each plugin, I changed some text in my article, hit the UPDATE button and reviewed the post on my site.
None of the plugins caused any problem until I re-enabled TinyMCE Advanced. Once I did, my post update turned up BLANK again.
Please note that I used only the visual editor tab and DID NOT switch to the HTML editor during these tests.
I disabled TinyMCE Advanced and all is fine now. TinyMCE Advanced is a great idea. Too bad it doesn't work.
