@vijay.seekout – Without a live link to look at, it is near impossible for me to determine what the cause of your issue is. But after rechecking the last Image i saw the link in the address bar and it appears you are using an outdated version (v4.6.3) of Rev Slider. Updating to the latest version (v4.6.5) will likely resolve the problem. Versions before this caused all kinds of JS errors when used with any other plugins requireing the GSAP animation plugin, which both Rev Slider and Popup Maker both use.
This was caused by the way they include the plugin in their own files and completely out of our control.
Updating to the latest version has worked for everyone else with this issue.
