Thank you, Steve Stern.
There was a plugin problem and finally solved it.
was it mapify pro? how did you solve it?
@ukeboyska – I have mapify pro installed and have this same error on my site as well.
Deactivate plugins one by one and identify a plugin that causes the problem.
@ukeboyska @runoffmedia – did you guys contact mapify support or were you able to solve it?

i contacted support and apparently mapify pro doesn’t work with wordpress 4.7 … they’re working on a fix.
aaand they’ve fixed the issue. except, as you probably know, mapify pro doesn’t offer auto updates…you have to download the new version on their site through your account (https://mapifypro.com/my-account/downloads/), deactivate your plugin, and reactivate after putting the new version up.
Josh here, author of MapifyPro. As mentioned this was indeed a compatibility issue with WordPress 4.7, and we have resolved the issue. The update is now live and can be downloaded from your account area. We are also working on a new auto-update feature for obvious reasons, but exploring the leanest option as the one offered by woo-commerce has caused too many issues with customers. We’re definitely aware of the frustrations however and should have a solution soon. Thanks!
Josh
