I post only to confirm that I have a similar issue.
I have enabled the Crayon Button to Post code over the crayon Popup.
It inserts allways the pre Tag with a class attribute.
If I Post as Admin with Crayon Syntax Highlighter in bbPress all is fine.
If I post as a User the angle brackets of the preliminary pre Tag are geting masked like so:
& lt; pre class=”lang:arduino decode:true crayon-selected” & gt;
If I remove the class attribute and put in a simple < pre > all works fine.
@netweb Thank you for your workaround I will Ty it!
