WC 2.6 issues
Yes, this is happening on our site too. Besides the Shop as Customer drop down not working, it also interferes with the WordPress drop down in the upper right too which prevents us from being able to log out of WordPress. Shop as Customer also interferes with the Slider Revolution plugin which prevents us from being able to click on tabs inside of the Slider Revolution admin area. When I disable Shop as Customer, everything else works as normal. Please update your plugin as soon as possible. Thank you.
We are also having these issues, not to mention that we cannot create an order without the payment information. This makes the entire plugin useless! If we cannot set up the order for sending an invoice or allowing our customers to easily log in and pay for the open order, then the entire point of the plugin is lost. We love this program and would not have updated to WC 2.6 if we knew this plug in was not compatible with it, but now we cannot go back.
Please get an update ready as soon as you can.
I was able to use the find customer option after I used a forced reload after emptying the cache, some of the old Jquery was still in there. Also it looks like you must hit the enter/return key after loading in your search string before it starts looking, this is different than the previous version.
Since so many plugins use Jquery I have found that conflicts between plugins are becoming more commonplace. Maybe deactivate all other plugins then force a hard reload of your dashboard to make certain it is not a conflict error.
