Not a bug XF 2.3 - Using the [IMG] tag for webp and pnj files breaks the site

Affected version

2.3

I tried searching but didn't see anything for this. I'm having an issue where users are trying to embed webp and pnj files (yes pnj, not png...Tumblr apparently) and it's causing site issues (layout becomes messed up, occasionally generates errors trying to access latest post).

An example:

It does this even with no add-ons installed and with the default theme... but doesn't seem to happen here and I assume the site is 2.3

I believe I've figured it out, this came over with an upgrade from 1.5.24. I'm assuming the IMG tag was a custom BB code previously

Actually even with the code disabled I'm still having issues, there seems to be some conflicts perhaps related to the size parameter

You can probably delete or close this thread, I think there are conflicts between the old custom IMG bbcode that was used in Xenforo 1 and how it works in Xenforo 2
