If you encounter a "Missing Theme" error message on your website's frontend, it may be due to not properly transferring theme files from a local testing environment to the live site.
To resolve this issue, follow these steps:
-
Re-upload all theme files via SFTP. If the screen remains white, proceed with the following:
-
Access your Control Panel’s File Manager.
-
Navigate to the wp-content folder.
-
Rename the theme folder to disable it.
-
If the theme was causing the issue, you should now be able to log in to your website via wp-admin.
To fix the theme problem, you have a few options:
-
Choose a completely different theme.
-
Roll back the WordPress theme to a previous version by downloading it or restoring it from a backup.
-
Contact the Theme Developer to report the issue and find out when they will release a patch, then reinstall the theme once the update is available.
