Pop Up windows don't close

Most likely a javascript issue.

Can you please read the section on how to Diagnose Javascript in your Browser… and let me know if you are receiving any errors when you attempt to close the pop-up window?

Thanks.

Error still occurred when in debug mode on multiple browsers. The following is the only thing that showed in the error console:

“Deprecated TinyMCE API call: <target>.onNodeChange.add(..)”

If I continue to press ‘ok’, (for instance: adding an anchor) it will continue to add anchor after anchor, yet the X and cancel do nothing. The grayed background goes away after the first click of the ‘ok’ button, and I can interact normally with the webpage (albeit, around the popup box).

Okay… it looks like you have something which is using an outdated tinymce api call.

That warning message is added by WordPress… to let you know a plugin or theme is using an outdated function call.

Does this still happen if you deactivate all plugins and switch to the default 2015 theme?

If not, then you need to track down which plugin/theme option is throwing this error. You can enable a few plugins at a time; going back to see if the error is thrown again. Eventually, you’ll narrow it down to a particular plugin that is causing the warning.

Thanks for your help. I will wait until they have updated to the most recent wordpress version and see if that helps. After that, I will start narrowing down the plugin culprit!
