WordPress 3.9 includes TinyMCE 4.0.* which is quite different internally than versions of TinyMCE in past editions of WordPress. This includes the TinyMCE APIs as well. Unless the plugin authors have rewritten the 9 plugins you use to be compatible with WordPress 3.9 and TinyMCE 4.0.* they probably won’t work. The best thing you can do at this point is to contact the authors of these plugins to see if they’re aware of this. If the plugin is still under development and hasn’t been abandoned, the author should already be working on an updated version.
It’s very important that users do this, especially users that don’t regularly “police” their plugins and themes to see if they actually are still under development (I don’t mean you specifically) as well as alerting plugin and theme authors who may not be aware of the changes in WordPress 3.9. They should but sometimes there’s the exception.
Ironically, all the plugins I use that add icons to the editor still work.
Is this happening on the TEXT editor, or the visual editor?
There’s a class change and plugin authors will have to update, instead of:
div.wp-menu-image.dashicons.dashicons-custom-plugin-name:before
They’ll have to use:
div.wp-menu-image.dashicons-before.dashicons-custom-plugin-name:before
It’s the “-before” after dashicons that was added.
webdevmattcrom – I think we’re talking about the ones on the editor not the admin sidebar 🙂 Could be wrong, though.
Not sure how this is related to an issue with the new version but none of the plugins that usually create their own icon in the text editor for posts and pages have their icons show up in that editor.
That sounded like the editors.
Ah! I see that now in the OP: “in the editor”.
