Did the 3.7.1 update on a Multisite install and now have two issues. Not sure how to resolve. This may be specific to our configuration. We have a load-balanced set up.
After the update, I got this error:
Fatal error: Call to undefined function wp_using_ext_object_cache() in D:\Sites\pages-pharmacy\wp-includes\option.php on line 170
I then replaced the /wp-admin/ folder with a copy of the folder PRIOR to the update.
The site would then open and run, but trying to open anything in the /wp-admin/ for any of the included sites takes 3-5 seconds. For example, get into a site admin, click on "all posts" wait 5 sec, ad screen refreshes. Click on "add new" wait 5 sec, for the screen to refresh.
The slowness ONLY happens for the /wp-admin/ stuff. The end user experience is not affected at all.
At the top of every admin page, I see this:
Thank you for Updating! Please visit the Upgrade Network page to update all your sites.
If I click the link for Upgrade Network, it tells me the Network is upgraded, but the message remains at the top of all admin pages.
All help appreciated. THX
