    Hello! I am receiving this message on my admin page: Failed to load plugin: nonbreaking from url https……./wp-content/plugins/tinymce-advanced/mce/nonbreaking/plugin.min.js

    I’ve tried to uninstall/reinstall the plugin but is not working anymore. No changes were made in the website (new plugins, theme updates, etc).

    Any tip here?

    Thanks in advance,
    Renato

    I have the same thing… I even tried to “Rollback” to the previous version and I’m getting it as well.

    Hmmm, files don’t just “disappear” from servers 🙂

    Can you try to load that file URL in the browser? What do you see? If it is a 404 page, perhaps contact your hosting provider. That file exists in the plugin and should be on the server, especially if you have reinstalled the plugin recently.

    Alternatively, if you have FTP access to your site, have a look at that directory to make sure the file is actually there.

    Hi Andrew! I found the file referred in the right folder, but this error message is still appearing.

    I’m afraid I have to confirm this. The error message also showed up here.

    However, I tested on several systems and found out the error only appears in the Chrome browser on my iMac. No problem with Safari and Firefox !
    The weird thing is that there is also NO problem on Chrome on my MacBook Pro.

    So, it seems iMac related and Chrome only.

    Reinstalling WP + deleting and reinstalling TinyMCE Advanced also did not work.

    @schirmer_rs, @gotmedia, can you confirm you are working on iMac also ?

    @schirmer_rs @dirkd hmm, this is very weird indeed. Any chance this is caused by a browser plugin/addon? In Chrome you can try loading the Edit Post screen in an “incognito” window.

    Another thing that might give some clues is trying to load that js file directly. I.e. go to [site.url]/wp-content/plugins/tinymce-advanced/mce/nonbreaking/plugin.min.js and look for errors in the browser tools.

    Yes, I’m on a Mac as well, the Macbook Pro and I’m using OPERA.

    I wound up deleting the plugin completely, as it was concerning me. I even had a developer look into it, but he can’t replicate the issue. I think because he’s not on a Mac, now that I’m reading your posts.

    Hi @dirkd,

    Using MacBook + Chrome as well. I’ve restore my full site (including the plugin’s previous version), and now all is well again.

    Hi Andrew,

    I will try to update the plugin to the last version available again, in a few days. If the error persists, I’ll access the address you have informed ([site.url]/wp-content/plugins/tinymce-advanced/mce/nonbreaking/plugin.min.js) and post here the results.

    Thanks a lot for your answer.

    Hello Andrew,

    – Chrome Incognito screen has no effect. Error still present.
    – Removed all my browser extensions : no effect
    – Opened [site.url]/wp-content/plugins/tinymce-advanced/mce/nonbreaking/plugin.min.js : no errors in the console

    But then I deleted TinyMCE Advanced and reinstalled the previous version 4.7.11. Now the error is gone, just as Renato already wrote above.
    Maybe this might help you to find out what is causing the issue in 4.8.0 ?

    @azaozz,
    Cannot get rid of the error. Have to stick to 4.7.11 or use another browser (which I don’t prefer). Any ideas how to solve it ?

    @dirkd when you loaded
    [site.url]/wp-content/plugins/tinymce-advanced/mce/nonbreaking/plugin.min.js
    in the browser what was on the screen? Did you see the JS “source”? You should be seeing something like:

    !function(){"use strict";var n=tinymce.util.Tools.resolve("tinymce.PluginManager"),i=function(n,e){var t,i=(t=n).plugins.visualchars&&t.plugins...

    (this is the minified JS source). If not, try holding down Shift and reloading the page a few times. If still no good, there is -something- that blocks that script from loading. The weird thing is that it is blocked only in one browser, so it must be something in the browser that does it…

    Alternatively, if you have FTP access to your site, try upgrading the TinyMCE Advanced plugin “the old-fashioned way”: upload the files with FTP. That may fix it in some cases.

    @azaozz Yes, I saw the JS source.
    But, I can inform you now that it mysteriously works again.
    I uninstalled the plugin. Then emptied the SG cache and cleaned up the database.
    Reinstalled the plugin and noticed the error disappeared.
    Don’t really know what caused the issue. But I’m glad it’s working normally again.
    Thanks for the good feedback here ! 🙂

    These errors are usually caused by (in that order):

    1. Some (perhaps misconfigured) security checks/filtering that triggers a “false positive”.
    2. Improper file permissions on the server. This may be an indication of “tampering” with the file in question. Best fixed by reinstalling the plugin.
    3. Caching problems, usually not in the browser but somewhere on the way between your ISP and the server. These errors usually “magically” disappear by themselves after a while. To eventually speed that up you’ll need to reload the page while holding down Shift a few times.

    Trying to access the file in question directly in the browser by copying and pasting the URL to it may give more info about what’s going on or help fix caching issues.
