Footer credit not removed and mobile menu not working

Hello,

I have an active Nicepage license, but the footer message
“This WordPress Theme was created with Nicepage Builder” still appears on my website, even though the license is properly activated. I have tried removing it from the footer editor and cleared the site cache, but the message remains visible.

Additionally, the hamburger menu on the mobile view is not functioning properly — it does not open when clicked, which prevents users from navigating the site on mobile devices.

You can view the issue directly at:

I would really appreciate your help in resolving both issues.

Best regards,
