an error occurred while processing the directive]

Hey @arskrigitsioniets, that’s a new one! Although I see another plugin had a similar issue: https://wordpress.org/support/topic/an-error-occurred-while-processing-the-directive-2/

What web browser are you using? And sorry, which language is your site in?

Hmmm I’ve switched my site to use Russian and am trying it with Chrome, but am not seeing that error.

However, I did notice that, at that spot, we have an HTML comment <!--#poststuff--> (its being added in includes/phtmls/yarpp_options.html on line 50), which seems awfully similar to the problem in this other plugin: https://github.com/ahmedkaludi/accelerated-mobile-pages/issues/1179. And no, to my knowledge, that comment has no purpose, so I think we’ll remove it in an upcoming release.
I’ll try to ping you here when that release is out, it will be nice to confirm this issue is fixed.

Air guitar 🎸!
