Sticky header only works in CUSTOMIZE section, but not in production site or mobile.
Can you show us your website address? SO that we can check what is going wrong. Also make sure,
- The theme is up-to-date and the companion plugin is up-to-date too.
- Try disable all the third party plugin you installed, clear the cache and see that fixes anything.
If all fails, pass us the WP Login details so that we can check what is going wrong.
Let us know,
I can’t deactivate plugins, because it’s a production site.
But why it works on CUSTOMIZE preview but not in site?
“But why it works on CUSTOMIZE preview but not in site?” - That’s what we want to know as well, this is why it’s important to follow troubleshoot steps, deactivation of plugins will take only 1 - 2 minute and without doing this we cant identify the cause of problem
