Latest upgrade breaks Text Editor (Visual works)

[jenseo]

Hi! I just upgraded to the latest version, but unfortunately it breaks the WordPress Text Editor when writing a post. The bar for styling the post (Bold, Italic, Hyperlink etc) are gone. It's not gone when switching to Visual Editor, but to be honest, I hate that one.

I have tried deactivating WordPress SEO, and this solves the issue, so I think it's safe to say that it's this plugin having an issue.

Any ideas what might be happening?

Cannot reproduce.

Are there any JS errors in browser console?

Do you still experience it if you disable other plugins / switch to core theme?

[jenseo]

Found this in error console (using Chrome):

wp-seo-metabox.min.js:1 Uncaught TypeError: jQuery(...).autocomplete is not a function

[Rarst]

What about disabling other things?

[jenseo]

No change with all plugins disabled. The site has up to a 1000 visitors at the same time, so I can't change themes.

[Rarst]

Could you give me a link to live script so I compare to source?

[jenseo]

https://delbart.se/wp-content/plugins/wordpress-seo/js/wp-seo-metabox.min.js

Looks good.

Do you modify version of jQuery in site in any way? Which version/URL do you see loading?

[jenseo]

Not modifying jQuery, using the bundled version. This is what it says in source code:

<script type='text/javascript' src='//delbart.se/wp-admin/load-scripts.php?c=0&amp;load%5B%5D=jquery-core,jquery-migrate,utils,plupload&amp;ver=4.2.4'></script>

[Rarst]

Do you see any other copies of jQuery loading?

[jenseo]

Hmm, this seems to load at the end of the source code for some reason:

<script type='text/javascript' src='//delbart.se/wp-admin/load-scripts.php?c=0&amp;load%5B%5D=hoverIntent,common,admin-bar,heartbeat,autosave,suggest,wp-ajax-response,jquery-color,wp-lists,jquery-ui-core,jquery-ui-widget,j&amp;load%5B%5D=query-ui-mouse,jquery-ui-sortable,postbox,tags-box,post,editor-expand,thickbox,underscore,shortcode,backbone,wp-util,wp-backbone&amp;load%5B%5D=,media-models,wp-plupload,mediaelement,wp-mediaelement,media-views,media-editor,media-audiovideo,wp-playlist,mce-view,imgareasel&amp;load%5B%5D=ect,image-edit,svg-painter,wp-auth-check,jquery-ui-draggable,jquery-ui-slider,jquery-touch-punch,iris,wp-color-picker,jquery-ui-&amp;load%5B%5D=accordion,jquery-ui-tabs,word-count,editor,quicktags,wplink,media-upload&amp;ver=4.2.4'></script>

That is still WP, I would look for something else queueing its own or CDN copy... No other ideas about the error so far.

[jenseo]

Unfortunately no other jQuery-inclusions.

Problem is that it didn't work with all plugins except WP SEO deactivated, so it's probably not a conflict. Can't see that it could be a problem with my theme either.

[Rarst]

Do you have staging/testing site to try reproduce at?

[jenseo]

Tried it locally, and oddly enough, there it worked. No idea why it's not working online though.

The div that should contain the editor buttons is empty for some reason.

[Rarst]

Looking at your front end there is an extra copy of jQuery from Google CDN, loaded by something OptinMonsterApp. Can't say for sure if it's the cause of the issue though.

[jenseo]

That's weird, that isn't anything that I'm seeing. The issue was still there though, when the Optinmonster plugin was deactivated.

[Rarst]

Do you still experience the issue? Unfortunately no new information to reproduce or more reports since (which typically means it's a rare case).

[stormcunningham]

I just experienced exactly the same thing with the latest version of the Yoast SEO plugin: it makes the rich text editing menu disappear from the Text editing view in Wordpress. It's there in the Visual view, but like Jenseo indicates, the Visual view is buggy garbage.

Anyone running into this issue, be sure to test with the default theme as well as disabling other plugins. In my instance, it was a conflict with my theme.
