Theme preview generates Non-existent changeset UUID

  • Hi All,

    Moved our hand-cranked diving club website to wordpress a couple of years ago & its been a revelation in ease of use however one item has consistently not worked.
    To avoid trashing the existing site while developing the wordpress replacement I installed wordpress in a sub-directory (wordpress) & then redirected to that when complete.
    The thing that doesn’t work is trying to preview other themes:-
    I go to Appearance/Themes/Customise for a theme & the displayed page shows ‘Non-existent changeset UUID’
    Doing a search on this the advice is to change the WordPress Address (URL: https://wordpress.aerodivers.net) (which is & Site Address (URL:https://aerodivers.net) to the same value but I obviously cannot do this else my site wont work at all.
    I’d really like to experiment with a fresh look to the site but this just stops that dead.
    I’ve looked at moving the whole site into root but that looks risky & a lot of work & surely if there is the option to install into a sub-directory the functionality should work when you do that?
    Any help woold really be greatly appreciated!

  • Read this page, which is linked from the Settings > General page:

    When you say you “redirected to the subdirectory”, do you mean you actually have a Redirect rule in .htaccess or you pointed the domain to the wordpress subdirectory?

    I have WP installed in folders all the time, and I never have a problem with the changeset UUID. If this is a special case setup, perhaps there is a bug in the changeset logic that it exposes and we need a ticket written to fix it.

    Hi Joy,
    Many thanks for the quick response.
    I’ve checked my domain (aerodivers.net) & I have not pointed it at the wordpress subdirectory.
    I have two .htaccess files, one in root which has quite a lot in it including a bunch of stuff referring to W3TC (a caching plugin I used to have that doesn’t seem to have cleaned up after itself when I deleted it) and the following:-# BEGIN WordPress
    <IfModule mod_rewrite.c>
    RewriteEngine On
    RewriteBase /
    RewriteRule ^index\.php$ – [L]
    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteRule . /index.php [L]
    </IfModule>
    # END WordPress

    the other .htaccess is in the wordpress directory and only contains the following:-# BEGIN WordPress
    <IfModule mod_rewrite.c>
    RewriteEngine On
    RewriteBase /
    RewriteRule ^index\.php$ – [L]
    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteRule . /index.php [L]
    </IfModule>
    # END WordPress

    I also note the web page you directed me to indicates since my site is in a directory called wordpress my Settings/General WordPress Address URL should be https://aerodivers.net/wordpress not https://wordpress.aerodivers.net. I seem to recall trying that at some point in the past & then couldn’t get into my site but might this be a part of the cause?

    Also neither of the .htaccess files looks anywhere near as complex as those on that web page & certainly don’t mention the wordpress directory – another part of the cause?

    My index.php file however does contain the following:-

    define(‘WP_USE_THEMES’, true);

    /** Loads the WordPress Environment and Template */
    require( dirname( __FILE__ ) . ‘/wordpress/wp-blog-header.php’ );

    Does any of that help identify where the problem might be?

    Yes, if your directory is not a subdomain, it should be treated as the first example, not the second.
    Your index.php already has the wordpress directory in it (to load wp-blog-header), so I’m surprised that your site works if the WP address is incorrect.
    I would change it in Settings > General to https://aerodivers.net/wordpress and if you can’t get back in, go into the database with phpMyAdmin and change it back. If you can get in, be sure to save Permalinks twice.
