Adding a new Gridpane site must be done in a Chrome browser.

If everything goes well, you should be able to find the site in the site list and click the Single Sign-On icon (the little WordPress icon). That will get you into the back-end of the site even though you haven’t setup any credentials for the admin account yet. Sometimes the SSL setup is a little persnickety, so use the SSO button now to make sure it has worked, if not, the resolution depends on the problem.

Next, let’s go back to the Gridpane Sites tab.

Normally, WordPress will make sure you have the three most recent Twenty-Something themes installed every time it updates itself. To prevent that, edit file /var/www/sitename/user-configs.php and add this line:

add_filter('wp_is_application_passwords_available', '__return_false');

If this is a new site installation, go to /var/www/sitename/htdocs/wp-content/themes/ and delete the two oldest themes, leaving just the most recent one. If you’ll be migrating a theme over, after the import is done, go to the same directory and delete all of the twenty* themes, assuming they aren’t in use…you need to log into the site and check to see what the currently active theme is. If you do leave one of the twenty* themes available, turn on auto-updates.
