I want to achieve a clickable URL in my bibliography using \href. I'm using custom document class for my course work and xelatex, biber to compile in Linux. The problem is that after adding a hyperref package it causes an error.

Full LaTeX template repository.

Packages used:


If I try to add \usepackage{hyperref} I get this error:

[1] (./kursinis.toc
! Missing \endcsname inserted.
<to be read again> 
l.5 ...tentsline {section}{Įvadas}{2}{section*.2}


Lines which causes the error:


New paragraph here...

Software versions:

This is XeTeX, Version 3.14159265-2.6-0.99992 (TeX Live 2015/Debian) (preloaded format=xelatex)
biber version: 2.4
