The problem comes from WPSSO Core Pro plugin: https://wordpress.org/plugins/wpsso/

This plugin injects the the_content hook of WordPress page and crashes wpForo output. We've checked and didn't find a way to totally remove this plugin from forum page. There should be an option to disable WPSSO for forum page (/forum/). Unfortunately we didn't find any way to disable it.

I'm sorry but this problem cannot be fixed from wpForo side, this should be fixed from WPSSO side.

wpForo has built-in SEO system, it doesn't need any SEO solutions. We recomend you contact this plugin developers and ask them whether provide an option to disable WPSSO for certain page, or check the problem and find why it stops wpForo page loading process.
