I’ve got WordPress 1.5 up and running. When I use my old theme comments no longer seem to work…
sigh. So I’ll stick with this default until I can either fix the old one or re-customize a new one.
edit: fixed! I stuck in the new default theme’s comments.php into my old custom theme and that did the job. Not sure what I’d changed in there, but oh well.
I’d just like to give major thanks to this upgrade guide, which helped me avoid many pitfalls my (somewhat ill-guided) customizations could have caused.
