Resolved Posting to this vBulletin forum with file att. issue

[SkipRinPerth]

When I press "post" to foxit forum (had file attachment and tags) I get prompted to save a data file mime type "application/JSON", I cancel it and it returns to continue editing new post, no message that it has posted successfully even though post was done. I am guessing it is the "your post was successful" message.

Tried to do it a second time but only happened on my first post today, so resolved for now.
