I'd also add this CSS code to see the whole text. Currently, the end of post contents are not visible:

#wpforo #wpforo-wrap .wpforo-recent-wrap .wpforo-recent-content td.wpf-stext {
     white-space: normal;
}

Try this CSS code, it should fix the problem

#wpforo #wpforo-wrap .wpforo-recent-wrap table{display: block;}

Don't forget delete all caches and press ctrl+f5 on forum front-end before checking the result.

Yes, I understood, but this didn't help me. And the site is still running, moreover the errors don't seem to come from the optimization, because I have already deactivated them everywhere and nothing has changed. I've already written that.

I don't cache or optimize this site, only the pictures. I already deactivated this, but it doesn't work.

Do you understood what i posted? You have js and other errors in your pages.

Can't be sure from where they come, 99% of time they come from optimizations.

Maybe not related to your problem, still your site doesn't work right.
