We have a problem with our AcmeBlog install since day one, only on the production deployment. In localhost works fine. In production we get the following error when clicking on Customize anywhere but the big “Customize Your Site” on the dashboard.
Fatal error: Call to a member function set_return_url() on a non-object in /home/quinju/public_html/blog/wp-admin/customize.php on line 28
Any ideas how we can fix this issue? I tried a Re-Install of wordpress no effect.
Thanks!
