WP4.4 error 404 retrieving TinyMCE's plugin.js

    Yet another TinyMCE 404 thread.

    My wife’s site is running WordPress 4.4 and the Visual tab comes up blank. In the console I saw “Failed to load resource: the server responded with a status of 404 (Not Found)” for the URL /plugin.js?#### (I guess it’s a cache-buster parameter), which I assume is a redirect or URL rewrite for the true path /wp-includes/js/tinymce/plugins/wordpress/plugin.js.

    I downloaded a fresh copy of 4.4 and blew away the tinymce folder and re-uploaded from the zip, no luck.

    I saw somebody suggest adding define(‘CONCATENATE_SCRIPTS’, false); to wp-config.php, also no luck.

    I’m a .NET guy, not a PHP guy, and she hosted this on a friend’s server rather than one we own, so I’m limited to FTP in her site’s folder. I don’t know much else about the box. It did work about a year ago…

    Any help would be appreciated.

    Have you tried:
    – Flushing any caching plugins you might be running, as well as server and/or browser caches. Also, any op cache or content network cache, as well as Cloudflare, clear those caches.
    – deactivating ALL (yes all) plugins temporarily to see if this resolves the problem (plugin functions can interfere). If this works, re-activate them individually (one-by-one) to find the problematic plugin(s).
    – switching to the unedited default Theme (Twenty Sixteen, etc.) for a moment using the WP dashboard to rule out any theme-specific issue (theme functions can interfere like plugins).
    – If still no luck, try increasing memory available for php.

    Yes I flushed cache and deactivated plugins (the site only has one anti-spam plugin) without success, forgot to mention that.

    I don’t really know WP so I wasn’t sure if I could safely switch back to her lightly-customized theme after trying the default theme. But you say “for a moment” so I assume that should be possible?

    I just tried increasing memory to 96MB but this had no effect.

    It should be safe.

    If no dice, then try MANUALLY updating. Download a fresh copy of the WordPress .zip file to your computer, unzip it, and use that to copy up all files and folders EXCEPT the wp-config.php file and the /wp-content/ directory. You may need to delete the old wp-admin and wp-includes folders and files on your server before uploading the new ones. Read the Manual Update directions first.
    – Backup: If you haven’t already done, always backup everything (including your database) before doing any actions, just in case something really goes wrong.

    Thanks. The default theme didn’t fix it either. I suppose I’ll try a full reinstall a bit later.

    – If all the above steps do not resolve the issue, then try MANUALLY updating.

    Yesterday it auto-updated to 4.4.1 … the problem still exists. Is auto-update any different from the full manual reinstall?

    In case the auto update did not complete, try try MANUALLY updating. Follow directions in my previous reply.

    Finally got around to doing the manual update. It did not fix the problem. Same “failed to load” resource error shows in the log. The file is there, permissions are correct, and I re-downloaded it and verified it matches the one from the zip file.
