So, here's my story.
I'm building a site and decided to create a custom 404 error page (still in the works). I found documentation that described how to add this page to the .htaccess page. Unfortunately, I assumed the .htaccess page was only used for the 404 error page and so created that file and added that single line of code to reference the 404 page. Then, I published my site, overrighting the .htaccess file that was already in place.
When finished, I headed to my site and got an error (500). A bit further research and I realized in a right quick hurry I had just screwed up by getting rid of that old .htaccess file. I copied a single line of code that got my site working...mostly. I thought all was good but I am still having trouble with pages in subdirectories. Here's an example - I used to visit www.mysite.com/subfolder and a default page for that folder would load like www.mysite.com/subfolder/default_page.html or whatever. Now, when I key www.mysite.com/subfolder, I get the 404 error page. It's as if it's trying to find a page that doesn't exist.
Even stranger, if I type the full path in the address bar www.mysite.com/subfolder/default_page.html, I get another error. I've checked the file on the web server and see that it does, in fact, exist and the code looks fine for that page.
As such, I'm assuming this goes back to me blowing away my .htaccess file. I've been trying to find documentation online, with no luck thus far, that will explain how to set that default_page.html file as the default page for that sub folder.
Any ideas? If not, I really just shot myself in the foot.
