Fatal error: Cannot redeclare

Seems like page is working…Can you please explain where did the error occurred?

I delete it form that page.

See this one https://estrella.pauloalves.net/trabaja-en-estrella/

Is the error is thrown after activating WP Job Openings? Please make sure by deactivating WP Job Openings plugin and check the same page.

Same problem.
But I deactivated the Yoast plugin and it fix the page.

You mean after deactivating WP Job Openings plugin the error is still there…right?

Yes, after deactivating WP Job Openings plugin the error is still there.

But when I deactivating the Yoast plugin its fix.

OK. Then, it’s not the problem with WP Job Openings plugin. It may be because of Yoast having conflict with other plugins (may be with hybrid composer).

ok, Thx
