So, I'm a noob. Here's my site: http://0371794.netsolhost.com/wordpress/
I changed the WordPress Address (URL) and Site Address (URL) fields and it broke the site (couldn't access anything). So I did some googling, and followed this guide: http://codex.wordpress.org/Changing_The_Site_URL using the Functions.php step. I made the edits to the functions.php file, accessed the site, and then removed the edits, just as the guide said.
Now my homepage and dashboard are accessible, but all of my secondary pages are not! What's up?? I'm at a loss, slightly freaked out, and would really appreciate the help. Please let me know if I need to give you guys more details.
