Missing argument

I have the same error in WP 3.7 + WordPress SEO 1.4.19 (but I already had it in WP SEO 1.4.18).

Solved in WP SEO 1.4.19. Please upgrade. For more information, have a look at this thread.

Please mark this topic resolved.

Additionally:

The issue is solved in 1.4.19, the only time you will still see the message is when you upgrade the WPSEO plugin as at that time you are still using the old version, any new upgrades of themes and plugins (after the WPSEO upgrade) should not give the error message.
