Error showing game to not logged in users

[naujoel]

Surprisingly, when a user is not logged in to my website, the plugin looks bad, but when logged in it looks perfect. You can view screenshots attached:

I've tried a lot of things but obviously I haven't tried everything yet.

I have tried changing the permissions of the files and directories to 777; I have purged the site and browser caches several times, until disabling them completely; I have checked that javascript is activated in the different browsers; I have tried several WordPress themes and the same thing happens in all of them; I have set the default Wordpress .htaccess; The site works fine with all the plugins installed, it only happens with this one...

So I don't know what I can do anymore.

Has this problem happened to anyone else? is there a solution for this problem? Thank you.

What is the address of your website ? (typically the address of a page/post with this game)

Hello, thanks for answering. You can see the error in the following link: https://www.chesscampus.com/nepomniachtchi-vs-wang-hao-torneo-de-candidatos-2020/

Have you tried to disable lazy-loading of RPBChessboard-related CSS/JavaScript files? In settings > RPB Chessboard > Compatibility settings.

And by the way, there are some JavaScript errors on the page (see in the JavaScript console, available with F12 on Chrome or FF):

This is not related to RPB Chessboard (it looks like the theme tries to fetch the user's avatar, which is of course not available since no user is logged), but it may impact it if the error is not caught properly. I suggest you report the problem to the theme author.

Thanks for your quick response. We have managed to solve it. It was indeed a problem with the Wordpress theme:
