I have an error, that goes away after I disable the woocommerce plugin. I want to add new page in my menu, but my menus aren't showing at all. And I get an error:
Uncaught ReferenceError: columns is not defined in load-scripts.php
I looked at similar issues, and I found about ' Bad Query Strings', but I don't know about this and where to fix it.
Also it just happened all of a sudden. Everything worked just fine only an hour ago :\
