Applying a patch manually​

If you are using XenForo 2.2.0 - 2.2.5​

Download the 220-225patch.zip file attached to this message. It will contain the following file:

1. src/XF/BbCode/Renderer/EditorHtml.php
2. src/XF/BbCode/Renderer/Html.php

If you are using XenForo 2.2.6 or above​

Download the 2211patch.zip file attached to this message. It will contain the following file:

1. src/XF/BbCode/Renderer/EditorHtml.php

Extract the zip file to your computer and upload the contents to the root of your XenForo installation. This should overwrite the files on your server with the new version.

Note: If you decide to patch the files instead of doing a full upgrade, your "File health check" will report this file as having "Unexpected contents". Because these files no longer contain the same contents your version of XF was shipped with, this is expected and can be safely ignored.

There is now an alternative manual patch available for customers using versions 2.2.0 - 2.2.5.
