I'm relatively new to wordpress. Migrating from an ancient html site.
I keep running into a problem where posts with lots (not really lots, but say 12 or so seems to be the limit) of images just simply won't publish or save drafts. I work for an hour, hit publish, and poof, page not found.
I can make small posts (5-6 images) and things are fine. Everything else is great. The first time I noticed this I went back and did everything again, which then worked. Since then I've been ctr-c'ing all content before hitting publish. But I've tried to publish this one post 100+ times, and it never goes.
The posts that have trouble can't autosave a draft either. It just sits there with the 'Saving Draft...' for hours and hours.
I've tried switching to Twentytwelve and twentyeleven.
I've tried disabling all plugins.
logging out and logging back in.
rebooting my computer.
starting over from a new scratch post.
I'm lost. Any ideas?
