Thesis 1.5 on WordPress 2.8RC

Due to my growth & multiple changes in my worldview over the years, this post is considered “archived” and is offered here for historical purposes only. Opinions offered above may not necessarily reflect my current beliefs, though you're still more than welcome to participate in the comments, discussing anything from the post. Thank you for understanding.

The next version of Thesis will include rockin’ WordPress 2.8 compatibility and work has progressed toward that end in SVN. However, if you’re wanting to use the latest, greatest version of WordPress, which is now available in release candidate flavor, you’re either going to have to survive without a widgets panel for the time being, or you can apply this quick fix.

By now, I hope you are running Thesis 1.5.1, which works perfectly with WordPress 2.8 (which you should also be running by now) and makes the following code edits completely unnecessary. Enjoy. :)

Open the file wp-content/themes/thesis/lib/admin/admin.php (your thesis/ directory may be named something else), and find this block of code:

function thesis_admin_styles_and_scripts() {
	global $wp_version;
	$new_admin_version = '2.7';
	$installed_version = $wp_version;

	if (version_compare($installed_version, $new_admin_version, '<')) {
		add_action('admin_head-design_page_thesis-options', 'thesis_options_stylesheet');
		add_action('admin_head-design_page_thesis-design-options', 'thesis_options_stylesheet');
		add_action('admin_print_scripts-design_page_thesis-options', 'thesis_options_js_deprecated');
		add_action('admin_print_scripts-design_page_thesis-design-options', 'thesis_options_js_deprecated');
	}
	else {
		add_action('admin_head', 'thesis_options_stylesheet');
		add_action('admin_head', 'thesis_options_js');
	}
}

That is the block of code which queues Thesis’ admin panel styles and JavaScript. The problem lies in that our JavaScript interferes with WordPress' new widget handling on the Widgets panel. This is simple enough to rectify. Once you've found the above block of code, replace it with this new block of code:

function thesis_admin_styles_and_scripts() {
	if ('themes.php' == basename($_SERVER['SCRIPT_FILENAME'])) {
		global $wp_version;
		$new_admin_version = '2.7';
		$installed_version = $wp_version;
	
		if (version_compare($installed_version, $new_admin_version, '<')) {
			add_action('admin_head-design_page_thesis-options', 'thesis_options_stylesheet');
			add_action('admin_head-design_page_thesis-design-options', 'thesis_options_stylesheet');
			add_action('admin_print_scripts-design_page_thesis-options', 'thesis_options_js_deprecated');
			add_action('admin_print_scripts-design_page_thesis-design-options', 'thesis_options_js_deprecated');
		}
		else {
			add_action('admin_head', 'thesis_options_stylesheet');
			add_action('admin_head', 'thesis_options_js');
		}
	}
}

Save the file, upload it to the proper place on your server, and enjoy!

Now for the following N.B., which I strongly suggest you do not skip if you are not prepared to troubleshoot things that go wrong:

If you're not using WordPress 2.8, there's no need to make the above change!

If you're not using version 1.5 of Thesis, you may not have to do anything. Honestly, I don't know as older versions are not being tested against cutting edge WordPress code. You are urged to upgrade to Thesis 1.5.

Ordinarily, core edits of Thesis are not only not encouraged but are actively discouraged in the interest of quick and easy upgrades. In this instance, because the upgrade will alleviate the need to make this core file modification, there's no risk. Enjoy.

Okay, I lied when I said there was no risk! Modifying core files can completely and utterly destroy your site! Ensure that you have an unchanged, working copy of wp-content/themes/thesis/lib/admin/admin.php so that you can revert back to if need be.

Everything else in Thesis should work fine on the new version of WordPress, but if any other issues come up, please report it on our support forums! Your help in reporting bugs helps make Thesis better for everyone!
