What ?: Error msg: OOps, une erreur est survenue, merci de renouveler votre demande.
Impossible to add some code from group admin page. I can only add snippet through forum answers.
Backslashes don't show up in code when directly inserted into forum post, even when removing the filter bp_get_the_topic_post_content', 'stripslashes_deep'
It breaks also the SWA page, activity page posts answers don't no more show up when the plugin is activated. This occured also when using your trick described here:
The code output is Ok, but the SWA page isn't. (since BP 1.2.8)
