Suddenly it does not work

Hello,

On the presented site there are two codes written with the plugin. I used the standard format and it looked great.

But suddenly, today, I have discovered the format has changed and the code looks practically like plain text.

Is there any issue with the plugin? The site has not made any major update, so that I don’t understand what is going on.

Thanks for the support.
