Bug: Strict Standards. Only variables should pass by reference.

I'm developing with wp_debug turned on. I found Infinite SEO has a small bug which annoys me when I'm in the wp-admin.

wp_debug throws me a notice: Strict Standards. Only variables should pass by reference.

It is in line 245 in wpmu-dev-seo/wds-files/wds-core/admin/wds-core-admin.php

Please replace


return reset(array_keys($sections));

with my code below to get rid of the strict standards problem.


$array_keys_sections = array_keys($sections);

return reset($array_keys_sections);
