Finder keeps popping up with "there is no application set to open URL..."?
I have a Macbook Air that is running OS X Yosemite version 10.10.4 and Safari version 8.0.7 and I keep getting this pop up and it seems to be only when I log in to myfitnesspal.com and I cannot get rid of it. I am not running any extensions and have tried clearing my history and website data to no avail.
I have also been getting strange pop ups before this asking for my password to iCloud, Messages, and FaceTime. Any ideas on how to solve this problem?
MacBook Air (13-inch, Early 2014), OS X Yosemite (10.10.4)
