Can't add media files after updating

I have this problem too. I have one site which is working fine, I have cloned it using Duplicator, installed it at a new location and configured it. Some parts of the TinyMCE editor used for editing posts and pages do not work, notably the add link button now does nothing, neither does the add media button. I also think that if you try to switch to a different theme, this does not work either. I have used FTP to disable all of the plugins and the functionality returns. I then started disabling the various plugins. The one which is causing the issue is the latest version of MailPoet. I am running a 2010 child theme on WP 3.8.1 The version of MailPoet is 2.6.1. Please advise.

Exactly the same problem here. Can’t even switch between html and wysiwyg editor when writing a post. After the deactivation of Mailpoet everything works fine.
I hope guys will fix it soon ??

Same here – html / wysiwyg & add media doesn’t work after mailpoet newsletter update.

Same problem here, and inserting links doesn’t work either. Deactivating the plugin solves the problem.

same problem after update 2.6.1 > wysiwyg & add media doesn’t work

Same problem since last update 2.6.1, and can’t add tags

Exactly the same problem after updating this morning.
Cannot add media, cannot show the textual version of my content in the WYSIWYG…

back to 2.6 :o(

It seems to be a JavaScript typo error. Call to a function named memoize instead of memorize I guess…

Hope it helps…

Hi Everyone,

We’ve already fixed the problems we are just testing it further, the v2.6.2 will come with this problem resolved. We intend to release this week.
