It is solved!
Doing what you said did seem to work, even when I switched back to my custom theme. It turns out having %category% as my category perm. structure was what was screwing everything up.
For now I’ve stuck with /%category%/%postname%/ since everything is working and I like how my permalinks look that way. If I start seeing performance issues I’ll switch back to the %year% method.
Thanks for the help!
Well, right now the site is at:
http://edosco.com/7blr
One of the categories is
http://edosco.com/7blr/comics
Thanks for looking!
Well, I tried one that it recommends in that article: /%year%/%postname%/ but that doesn’t solve my problem.
I noticed that when I use the default permalinks for single posts but leave %category% for my category permalink structure, both are broken (i.e. going to mysite.com/mycategory gives me the no posts error).
