Hi There @LixarCommunity
Thanks for writing in! Upon checking, I see that you have 3 websites assigned to your Themeco licenses. I see two websites with sticky navbar functioning properly and the other one needs htaccess password to view your site. We need the correct site URL with access to check your issue.
In the meantime, make sure that you’re using the latest version of X/Pro theme by checking the latest version numbers from here (https://theme.co/changelog/). You can check our update guide here (https://theme.co/apex/forum/t/setup-updating-your-themes-and-plugins/62).
If you’re fully updated, then disable your 3rd party plugins and test your issue further. If you’re using a child theme, activate your parent theme and test your issue.
Thanks!
