Bug #55775
Updated by Stanislas Rolland almost 10 years ago
For some reason, IE 11 seems to think that the iframe document does not belong to the same domain as the document in which the RTE script is executing.
This is a major issue now that the TYPO3 backend uses
<pre>
<meta http-equiv="X-UA-Compatible" content="IE=edge,chrome=1" />
</pre>
The RTE does not work in IE in the TYPO3 backend.
