Duplicated content (forum)

[subpopet]

After migrating from All In SEO plugin and configuring Yoast I’ve found my forum page is duplicated at the top of the page. If I deactivate de SEO plugin everything goes back to normal

Does anybody know what can be the problem?

I can see the head opens on line 14 and closes on line 747, yoast opens on line 67 and closes on line 600, which clearly is not correct.
Have you tried disabling other plugins besides yoast?

I know you probably need these plugins, but disable them one by one until the problem goes away, then you will have to work on a fix.

To me, it looks like a conflict with plugins

Some plugins play nice, others do not.
