Hi. I had a theme a friend made for me ages ago, and today I replaced the colors/images on it to fit something else I was doing. The only problem was, when I put it on the page, the colors ect are fine, but the menu has completely disappeared, and in place of it there is just {MAIN_MENU}. :o
A la this:
http://srkonline.net/junkioppa/gallery
It's really odd, because other than replacing the title of the page and the image, nothing else was changed. The template works fine on the other page though, here:
http://www.srkonline.net/leejunki/gallery/
I don't understand why one shows fine and the other doesn't. :\
That theme is made for 1.3 and won't work correctly on a 1.4 gallery without updating it as described in the documentation. Both galleries need to be updated to 1.4.10, anything less is insecure and unsupported.
