Access to TinyMCE 4 via the CacheFly CDN is being removed on November 30 2020.

We previously announced the end of support for TinyMCE 4.x - officially supported through to December 31, 2020, which will enable us to focus more of our efforts on the roadmap for TinyMCE 5 and beyond.

Further to this, access to online services for TinyMCE 4 will be switched off on the following dates:

  • CacheFly CDN ( - November 30 2020
  • TinyMCE CDN ( - February 25th 2021
  • Tiny Cloud ( & - February 25th 2021

We recommend switching to Tiny Cloud and migrating to TinyMCE 5 as soon as possible to make sure you’re up to date with its advanced features and functionality.

To switch to Tiny Cloud, update the source of the TinyMCE script file in your HTML pages (replacing no-api-key with your own API key from your Tiny account dashboard):

<script src="" referrerpolicy="origin"></script>

When you switch to Tiny Cloud using the URL shown above, you will be upgraded automatically to the latest version of TinyMCE 5.

Depending on your configuration, you may need to make some additional changes - we recommend reading our guide on how to migrate from TinyMCE 4 to TinyMCE 5.

Note that, if you really need a little more time before making the switch to TinyMCE 5, you can switch to Tiny Cloud but stay on version 4 using the following URL:

<script src="" referrerpolicy="origin"></script>

Contact us for more assistance switching to Tiny Cloud, TinyMCE 5, or for any other information regarding these changes.
