To make fancybox works I had to add the code below to _config.php file
That cause Anchor tag - link to in same page not working properly.
<a href="#aaa">Link</a> .... <a name="aaa">Jump to here</a>
Now #aaa not take me to "Jump to here" in the same page but take me to mydomain.com/index.php/#Contact
What is the best way to fix this issue?
