headers displaying inconsistently

I can’t really see anything which could be wrong from here.

If you have a test site setup, perhaps send me login details for it so that I can have a poke around and see what is going on.

You should explain what you are trying to achieve.

If you are trying to have a different header image on specific pages, Weaver has several mechanisms for that, so you may not need that plugin.

On any given page, selecting a featured image that is as wide as the theme will automatically replace the header image for that page.

If you want to select a different header image for specific page types, like certain category pages or other, you can use Weaver Filter box to do that as explained in the thread below.

Thanks for sending login details.

If the Weaver theme is manipulating header images, then that might explain some weirdness.

Having said that, the plugin appears to be working just fine. The post which you said doesn’t show up a custom header does not have one set in the admin panel. The category is showing the one set in the admin panel and so are the posts which do have header images set.

That’s part of the problem. I will set the image and save it. Then when I go back to that file, there is no image set. Some of the pages just aren’t saving my settings and I can’t figure out why.
