Searched but can't find anything obvious that displays about this.

I have a user using UAM and front end editing. He's trying to create a link in an article to an external website.

He can edit the article and save it fine until he tries to add an external link to a piece of text. The link appears to create OK, then, when trying to save he get's access denied.

He's getting this on more than one article and in one there's already another external link set up, which saves just fine!!

I've checked via ACL manager and all permissions look correct at group and article level around content. UAM in theory just honours everything, it simply presents a list and calls the editor on the article. I've read through JCE docs and it doesn't appear to do validation on links at article save time.

So... before I start to try to problem solve by trial and error, is there anything in JCE that could be contributing to this behaviour? Have you seen something similar before?

Thanks.
