I have entered in the social media addresses for Facebook and LinkedIn - each time I test it, I get an error message that the page cannot be found. However when I paste that same address link directly into my internet browser (Firefox Version 48.01) it works. How do I fix this?
I took a look at those social media icons and I could see that the LinkedIn one wasn't working as you would expect. Basically what's throwing the URL off are the quotation marks. The fix is fairly simple, and that's to use this URL appendage:
in/eliseo-%22lee%22-diprinzio-ra-pp-a97b8314 (the http://www.linkedin.com/ is already implied with the social media buttons).
You'll see that in this URL the quotation marks are represented by their HTML equivalent. This is the true URL of the LinkedIn page which is translated within the browser to give something that appears more "tidy" but when taken literally is an invalid URL because the link stops at the first quotation mark when translated to HTML from the editor.
I found that URL by searching for the LinkedIn page in Google, and grabbing the URL of the link there.
