Hello there Marko, you need to go to appearance -> menus and create two custom links.
The one will be for galleries and will look like this: http://www.yoursite.com/galleries/ and the other one will be for discography and look like this http://www.yoursite.com/discography/
If you need to change the section title from discography to album, you can do that from appearance -> theme settings -> section titles.
Thanks again for support.
One more question? When I set gallery, and try to open "View set", inside images, it shows "twitter, facebook" etc. icons, so how to get rid of that please?
Sure Marko, check out this ticket http://cssigniter.ticksy.com/ticket/129449/ it will help.
Hello again !
Thanks for reply. I am not sure where to look and find those file?
Please let me know in more details as I am still learning those things, hope you don't mind?
Install the WPIDE plugin and on the right side you will notice a folder tree. Navigate to /wp-content/themes/wp_muzak5-vx.x/js/ and it will be there.
