From the screenshot you can see that, the the JD Seattle is still showing on mobile browsers but not on a computer it is also showing the Powered by asteroid framework which is not supposed to, from the smartslider i have changed those words but it still shows up when you use a mobile browser, please help.
The url is www.cavendishstaffinguk.com.

Secondly the mobile menu does not open up on UC browser but opens up on chrome mobile browser.

Hello,

Thanks for using our template.
It could be that's it's cache or something that it's still showing the same text on Mobile. Can you confirm if the text on desktop has been changed and what happens if you resize your desktop browser to the size of mobile (is it the desktop text or is it the mobile text (unchanged))?

We'll look at the UC browser issue and be back to you with more.

Thanks,
Chetan
