I (well, Fantastico) installed WordPress to use on my blog, Crooked Glasses, about a month ago, and since I have extensive experience with building HTML and CSS (and a tiny bit of PHP), I thought I could build my own theme for it, since I didn't want the default theme. I've had nothing but headaches and tears from it since.
The main problem is that the functions beginning with "wp_" don't work, except for wp_blog_header (I think). Every time I try to use one of these, I end up with a "fatal error: call to undefined function" that destroys my whole page. I've tried "wp_tag_cloud," "wp_list_pages", and the other function that allows you to call for a certain number of recent posts that I can't remember off the top of my head. Nothing "wp_"-related works.
I started out with my theme files in the base folder of the subdomain, because I didn't know any better, and that half-worked. Now, I've tried to install the files in the /themes/ directory, in a subdirectory called /glasses/. This, if possible, is WORSE. Now the theme won't even show up beyond the first page of posts, and all of the links to my pages and all the links to my categories are broken. I have no idea why.
I've been scared to post here for over a month because I didn't want to get completely owned and humiliated by people who know soooo much more about WordPress than I do, but I'm about sick over this. I have scoured forum posts and Internet articles, and have even bought a guidebook to try to learn about building WordPress themes, and I'm more confused than before. Someone, please help.
