Invalid argument error on Basic Options page

Hi @hatchb4ck, I can’t reproduce this so I’ll need some additional information:

What PHP version are you using?

A url to the archive page itself.

Which archive page settings are you using?

Thanks!

Basically, we’ve got two issues going on: with the option page, and then with the archive page.

Right now, I still can’t reproduce the error but I may have an idea of what is causing the problem–it’s likely the drop-down grouping by post-type. That addition caused me a lot of issues in initial development, one of which was a problematic “invalid foreach” error that seemed to randomly crop up. I’m going to remove that with the next RC version if it’s causing other users problems. On that note: do you have any Comic Pages (new post-type added in this version) created?

I looked at your archive page, and compared with the settings you provided in my environment–it’s working as expected. Basically, it’s hard to tell if ordering is working properly because your comic posts all have the same date.

Side-note: if you want to get rid of the default styling for the gallery, there’s a filter that you can override like so:
add_filter('mangapress_archive_gallery_style', '__return_empty_string');

Thanks for the additional information!
