Forum Image/Video embed not accepting button clicks when second image is attempted to be posted.
 

Hi there, having a very weird problem in my forum and I really cannot figure out why. For reference, running 4.2.0 PL2.

I've had a few members come to me and indicate that when they try to link an image or embed a video using the buttons on the reply fields, that it will accept the first such case, but in the second, no matter how often they click "OK" it never properly adds the second image. I tried it myself and originally thought it was a problem with the [video] BBCode, but as it turned out, it applies to both - if I put both in the same post, the first one will always succeed and be embedded when I click OK, but it will fail on the second one. A few people reported it fails even on the first one, although I've not been able to reproduce that.

I'm not sure how I could check around or resolve this issue. It's obviously something wacky with Javascript, but I'm not sure where to begin. A scan in the AdminCP (Maintenance > Diagnostics) revealed that some files were not part of vBulletin (but I know these are mods I installed or possibly outdated files) but a few did not have the expected contents. A quick check though revealed it was just the headers being different (probably due to PL2 being a hotfix) so it seems to be nothing weird with any of my files.

Unless, of course, this turns out to be a legitimate bug, but I'm a lot less confident on that. I think something's messing up with how Javascript handles something, somewhere.
