Paginate reply on any pages same articles….

Regardless of how a post is broken into pages, automatically or manually, the resulting page links at the bottom is a core function that gets the page counts from a global variable established when each post is setup in the Loop.

If the thumbnail plugin is fouling up this core functionality, then the plugin is simply not compatible with multipage posts. I’ve no idea why, you don’t indicate what plugin this is. It may be easy or difficult to make it compatible. It’s probably best to bring this to the plugin author’s attention.

Thanks…

Plugin is “WP Category Thumbnail”.

I didn’t see anything obvious in the plugin source code that would foul up post page numbers. I was unable to cause any issues by using this plugin on my site, but I have limited posts with multiple pages, and there are only a few pages on any of them. So I’m not sure where the problem lies, sorry.

This plugin has not been updated in a while, there will be growing concerns of compatibility with newer versions of WP, and one should never forgo core updates for the sake of plugin compatibility.
