I installed WP1.5, typed a couple of entries, and then let it rest for awhile. Today I went back and when I tried to get into the login screen, I got a 500 error. Did a forum search and someone said that the .htaccess file was a problem and to delete it.
I'm too cautious to delete, so I renamed the file and tried login again. This time it worked, but got a 404 error when I tried to view my previous posts.
Because of the original 500 error, I figured that maybe something got messed up and I deleted the posts. Then I tried reposting. Now I get the index file but can't get the archive file.
I found this post: http://wordpress.org/support/topic.php?id=13954#post-163746
After all the discussion in that post, it would appear to be .htaccess again. One poster, Yingjai, talks about an apache config file. I don't see that in my directory.
How do I go about fixing this?
