Really erratic behavior for TinyMCE after WP update

  • Hello, I have been looking high and low for a solution to this, with no luck. I’ve got a site freshly developed which is ready to go live, the client loves it, but after upgrading to wp 3.5.1 the TinyMCE editor is acting very odd.

    Firstly, my editing window in the admin area is huge, the iframe is getting an inline style of 4229px tall. Also, when editing contents in the visual editor, the enter and shift+enter paragraph and line breaks are causing all kinds of problems.
    Paste as plain text is creating new paragraphs for each line, and the text is italicised. When I try and clean up the spaces by backspacing one line to the previous line and then shift+enter for a line break, then the curser jumps up to the last text with formatting (an h2 a few lines up) and applies the backspace there, and then italicises the text below it.
    If this description doesn’t make much sense, trust me I understand. The editing window is behaving VERY oddly.

    I have tried deactivating all plugins, switching to twentytwelve theme, no luck. I have tried the ‘Manual Upgrade’ from the codex https://codex.www.ads-software.com/Updating_WordPress
    to make sure all files were copied correctly… no luck.

    Any ideas? We entered a good amount of info into custom post types before we noticed TinyMCE was busted, so can’t go back to backups.

    Thanks wp folks.

    Thanks esmi, I’ve tried that, as well as trying other browsers and other computers, still getting the erratic behavior.

    Interestingly, when I log in as another user the editing window is the regular size, but the funky editing behavior still persists.

    Any other ideas? Thanks again.

    Is there a way to manually re-install TinyMCE? Anyone else experience this before?

    Try re-uploading all files & folders – except the wp-content folder – from a fresh download of WordPress. Make sure that you delete the old copies of files & folder before uploading the new ones.

    Having the exact same issue, any pasted content into the window and then removing line breaks causes additional <em> styles to be applied with a tiny mce class. and incorrect positioning of cursor to where the focus actually is.

    the code that seems to be embedded when deleting a carriage return is

    <em id="__mceDel">

    I tried re-uploading the core files, no luck. I was going to try a second time to make sure all the files were there, and I thought first I’d try an easy fix… installed the CKEditor for the first time… problem is gone. Not to mention CKEditor comes with some great features (custom button configuration right from the wp admin area, easy custom styles)

    So, not really a fix, but I like the CKEditor enough that it may be in my stock install arsenal from now on.
