Hi, I have two issues with the Jevelin theme right now.
1. The search button appears on my header, but when I click it nothing happens.
2. The menu on the header changes on mobile mode as it should be, but when I click on it it’s supposed to drop down and allow me to see the different options, however nothing happens just like in the search box.
This can be due to plugin conflict on your site so please try temporary deactivating all plugins except Unyson plugin and see whether everything works fine and then enable the plugins one by one to see which plugin is conflicting if any.
Also please clear the Endurance Page Cache that you are using on your site.
Awesome great to see you got the issue found.
based on this page — https://github.com/bluehost/endurance-page-cache — I’d say it’s a plugin from BlueHost, probably installed as an MU plugin. If you have questions about it, please contact their tech support.
