Hi, can anyone please help? im getting this strict standard warning everywhere on my wp-admin
Strict Standards: call_user_func_array() expects parameter 1 to be a valid callback, non-static method yiwProductsPricesFilter::admin_init() should not be called statically in /usr/home/chinat/www/htdocs/wp-includes/plugin.php on line 406
I've recently downgraded my site from a multisite to a regular wordpress site. Then after moving it's url, i've readded the multisite. However, the new site i've added doesnt show up under the My Sites drop down and is only able to be accessed when i go into my admin > my sites. Im not sure if its an issue i've caused during the movement/setup that has caused this strict standard to appear.
Also, during the process, i've upgraded my wordpress to 3.6. Could that be the cause?
