Dear Olga,
Will we find what we are looking for when we install this plugin. I thought we already had the Xstore child theme and everything on our site is under the child theme?
The one you are talking about, is this another child theme?
Also, as per the screenshot, there are problems trying to upload this Zip. http://prntscr.com/gx0jj5 so hope you can help.
Once installed, will we be able to go in and rempve the two sort by items that are not required?
