Before the upgrade there was no any problem, and I gave you the permission to help with the plugin woodmart-core which has occured this problem. So what about just to help????
But it has the relation to the last update!!!!!!!! What kind of files where changed???? That after the update multisite stopped to response correctly????
If you want, we can send you a previous version of the theme so you can see that it is not related to the update. Please, specify the version number and send us your email. We will send you the theme package.
