[Plugin: Viper's Video Quicktags] Plugin won't work

Hi,

I have been using this plugin before on this site with absolutely no problems. However just recently i have noticed the plugin wont work and will only show the hyper-link for the videos.

for example:
https://www.animesenpai.com/watch/naruto-shippuuden-episode-3/online-free

i’m not too good when it comes to trouble shooting, so any help would be much appreciated

thanks.
