[Plugin: WordPress SEO by Yoast] Title & Metas => Empty Tabs

Found it, it’s a problem with ie9. When I switched over to Safari, all of a sudden it worked.

I have a brand new wordpress installation with no conflicting plugins (in fact no other plugins) and using twenty-eleven theme I am still getting this error.

Created a bug report at All in One Event Calendar Trac https://trac.theseednetwork.com/ticket/533

If you’re still having issues, please open a new thread, this one is closed.

I had the same problem and I came to the conclusion that the problem was not a conflict with another plugin but the PHP memory limit. Most likely when you disabled the All in One Event Calendar your freed up enough memory to load the SEO plugin properly but you would get the same by disabling one or more other plugins (All in One Event Calendar is a bit heavy on PHP so you might have to disable more than 1 plugin to get the same result).

To solve the problem increase PHP memory limit in php.ini:

memory_limit = 256M;

If you do not have permissions to change the settings in php.ini contact your hosting company and ask them to do so.

Hope that helps.

This did not work for me :(, still looking for a solution for this problem.

They have fixed this issue! Please delete your current All-in-One Event Calendar installation.

Did you try my suggestion?

I don’t use all in one calendar

I had the same problem. Also not using one calender and no conflict with other plugins.

I solved the problem. Do you have problems with loading a summary at your wordpress dashboard? It keeps saying loading plugins…, wordpress blog…, other wordpress news?

I went to dashboard – updates and I installed wordpress 3.5 again. All problems were solved.

Maybe you can try this?

yep

reinstalled WP 3.5 and SEO
no luck

could be one of these facebook or other javascript plugins causing this error? I don’t have the all in one but am having the exact same problem on WP 3.51 and latest Yoast SEO plugin…

Joost, just in case your interested in taking this further (I know it’s not your fault but some other plugin author that was a bit too creative):
