Just FYI, changing the media settings and adding the function to change the thumbnail sizes will do the same thing. So Regenerate Thumbnails is necessary for either case, though the plugin description doesn’t mention the manual method.

I think I see what the problem is. For your ‘page-header’ featured images, you don’t have to add add_theme_support() and set_post_thumbnail_size() to your functions.php file. Theme support for featured images is already added and you’re not changing the dimensions of the default featured images. You’re adding a new size.

Use add_image_size() as a replacement for the two functions you were using.

add_image_size( 'page-header', 1000, 300, true );

Then in the template files, use the_post_thumbnail('page-header');. Let me know if that works out as expected.

Are you regenerating thumbnails after the changes? Images thumbnail sizes are physically (digitally) created based on the functions you mentioned. So if certain dimensions are used to create thumbnails from a specific image, and then you change those dimensions, new thumbnail sizes need to be created based the new dimensions.

Install and activate Regenerate Thumbnails and give it a run (Tools menu). It’ll read your new functions, delete the old thumbnail sizes (but keep the original image), and then use the original image to generate new thumbnails. Clear your cache and refresh after that.

They seem to be showing up on single posts for me. I take it you’ve resolved the issue? If you still don’t see them, make sure your caches are cleared.

You don’t have to log into cPanel/FTP unless you choose to. The theme you purchased most likely comes in a zip file. With that, you can upload the theme through your WordPress dashboard. Follow these instructions, steps 1-3 and 6.

As for your old theme, it will remain installed on your site but it will no longer be active once the new theme is. However, you can switch back at anytime by going to the Appearance -> Themes menu and choosing to do so.

Actually, it looks like I have to disable both the “Likes” modules as well as the “Gravatar Hovercards” for it to work properly. I don’t no for sure if activating any of the modules that are deactivated by default will break it. I didn’t check. I can confirm those two modules cause a conflict, though.

A few months back, I released my responsive theme framework. It’s 100% GPL, 100% responsive (including drop down menus), and is sold alongside what I call “Child Theme Skeletons” that alter the structural CSS of the framework in ways that give you a head start on new, unique designs. There are no design options… it’s a true framework.

There are too many features to list here. Check it out at Volatyl Themes and let me know what you think.
