[SmartCrawl Pro] Https Mixed Content Errors

The above site is on https. However, because part of your code has a http instead of https, I'm facing the https mixed contents error. I believe it's from SmartCraw because the moment I disable it, the https mixed content error is gone. I tried to look for the code to change it myself but to no avail. Please advise where should I change them.

I'm pasting the codes for your reference:
