Only if you give us permission to deactivate your plugins. The issue does not happen on our installation which means it is specific to yours, the cause of this is normally a plugin conflict. So to test that we need to deactivate plugins
Hi,
I see that you are using any Server’s minify feature that cause to issue. All js and css files are minified in wrong way so your search is not working. Please contact at your hosting provider.
Thanks
