Hello,
Yes, the Ad widget will not work, if you don’t add the the url. We’ve clearly provided the instructions above in Ad Widget that How to use the Ad widget. I’m bit disappointed that you haven’t read it well.
You have to replace AD LINK Here with your Ad url, for Ex: Now I’ve set the http://google.com.
<a href="AD-LINK-HERE" target="_blank"><img src="BANNER-URL-HERE"/></a>
For Twitter, If you the tweet some more words, it will not be cropped out.
All your issues fixed. The Mobile Menu has some issues, when you put the logo in Header section.
However, we are taking your input and going to update the theme in 2 days With all problems fixed with some enhancements.
Cheers. Thanks for your support.
