Michael Beckwith on "[Plugin: Custom Post Type UI] All my custom post types are stripping out p and br tags"

Hello,

I've noticed that all my custom post types are stripping out any p and br tags so any paragraph breaks are removed, resulting in one long chink of text.

Is there a setting somewhere to fix this?

I don't have wpautop deactivated.

Not sure if this is down to wordpress or plugin. I've tried default theme and that doesn't fix it.

Can anyone please advise?

Thanks!

This would be WordPress or the theme or some other plugin running filters the post content. Nothing our plugin will be doing.
