Forget it.

It was due to WPEngine caching.

I had the issue with the new plugin too. I had to go into WPEngine and clear page cache to fix it. I’m assuming this was the real issue.

After researching, I discovered the root of the issue.

The PHP 5.3.9 update includes a new php.ini setting called max_input_vars. This new setting is a restriction on the number of data values that may be sent back to the server, and was added as an attempt to potentially avoid some dos attacks. However, due to the fact that saving a WordPress menu sends back a large number of values (multiple for each menu item, especially when using UberMenu), the values will be truncated to this limit. The default value for max_input_vars is 1000, and if the PHP server being used has not adjusted this value, the maximum number of menu items that may be added successfully (with the UberMenu) is something around 80. Any more will not only be cut off, but the set locations (under Manage Locations) may also be lost.

Here’s a detailed report

Bottom line is, if you don’t have access to the php.ini file (which you typically won’t), you’ll have to contact your host to get the value changed.

It’s a wordpress 3.9.1 bug. I’ve got the exact same problem. The similarity with your situation and mine is that I just updated WP, and now it fails. Request a bug-fix <del>or revert to a previous version</del>.

@esmi is right. I’ll look more deeply into it. I did deactivate all plugins, and reactivate all, but not individually.
