Try deleting post-options-thumbnail.php (I think it’s in the main directory) and see if that helps. I’ve still got the theme up and running fine in WordPress 4.7.2.

You have to first update the WordPress Options Framework (there’s a directory for it called “Framework” I think) by just Googling it and downloading the latest version (it’s the framework that the Theme is built on). Then you just copy over or replace the version that’s in the theme with the new version.

Then you’ll start to see error messages. You’ll have to modify two files: functions.php and post-thumbnail-template.php

Wordpress 4.6 included some lines in post-thumbnail-template.php that created conflicts with the theme’s functions.php. That’s why the theme crashes.

Also, the version of the Options Framework that’s in the latest version of the theme is from 2012 which is already 5 years old and needed to be updated anyway. They could fix this theme if they wanted to… but I don’t think they are supporting or selling it anymore.

Absolutely. I’ve actually figured out the problem though:

post-thumbnail-template.php was calling:

function the_post_thumbnail_caption( $post = null ) { echo apply_filters( 'the_post_thumbnail_caption', get_the_post_thumbnail_caption( $post ) ); }

…which I commented out.

I also updated the Options Framework since it was an old version from 2012.

From there I just followed the error messages and modified functions.php by commenting out Line 19 (which was calling the options framework uri which had already been called.)

Now it works.

I couldn’t even see an error message before I updated Options Framework. It was definitely pot-thumbnail-template.php from WordPress 4.6 that was causing the site to crash though…
