So, I know there's already a question about this (Hyperlink in moderncv with acrobat reader) but I have tried the solutions there (updating and security settings) and it still doesn't work and I don't think that it's an Adobe problem since I have other documents (not moderncv) where the links work perfectly.
I am using Adobe Acrobat Pro XI. The links do work on Preview.
Here's a MWE:
\documentclass[11pt,a4paper,dvipsnames]{moderncv}
\moderncvtheme[blue]{classic}
\usepackage[scale=0.8]{geometry}
\usepackage[utf8]{inputenc}
\firstname{First name}
\familyname{Last name}
\title{Curriculum Vitae}
\address{Address line 1}{Address line 2}
\mobile{Phone}
\email{Email}
\AtBeginDocument{\hypersetup{colorlinks, urlcolor=NavyBlue}}
\begin{document}
\section{Education}
\cventry{Year}{Degree}{University}{Location}{GPA. \href{http://www.google.com}{Google}}{}
\end{document}
Best Answer
On the moderncv.cls file I removed the baseurl= http:// option under hypersetup and it worked. I'm not sure why but it did.
