TinyMCE

The images not loading was probably cache related. I can see your site looking good.

For the error: I just updated the TinyMCE Advanced plugin, try the new version.

Hi,

I updated the plugin but still get an error: Failed to load plugin: charmap from url https://abctravel.nl/wp-includes/js/tinymce/plugins/charmap/plugin.min.js

This is a file from WordPress, not from this plugin. Opening the URL in a new tab seems to work properly. The file is definitely there and seems fine. Try opening it in a new tab and then refresh the Edit Post screen couple of times.

I tried to refresh but everytime there is an other file that failed.

https://abctravel.nl/wp-includes/js/tinymce/plugins/anchor/plugin.min.js

I also have problems with the plugin: WPBakery Page Builder Settings, there is an error that says: Important notice: You have an outdated version of WPBakery Page Builder Design Options. It is required to review and save it.

When I go to the design options and click on save I get this messages: Design Options could not be saved. Error: ‘//abctravel.nl/wp-content/plugins/js_composer/assets/less/shortcodes/vc_pie.less?v=5.4.2’ wasn’t found (522)

Do you think my updated to WordPress 4.9 went wrong? Do I need to go back to WordPress 4.8 to fix this?

I tried to refresh but everytime there is an other file that failed.

Sounds like there may be a problem with your hosting or some sort of timeout perhaps.

The other error may be from the builder plugin, or may be the same thing happening there too. Try accessing that file directly to make sure it exists and the permissions are right.

In either case contact your host’s support and ask them to look into these random errors.

I am getting the same issue after I have updated to wordpress 4.9. And I am getting this error.

Uncaught (in promise) TypeError: Cannot read property ‘getNotificationManagerImpl’ of undefined

Same problem here after updating to 4.9.1. like solutiondriven mentioned.
