You get the “Sorry, This txt file type Is Not Permitted for Security Reasons” error message when you try to import settings file type that’s not supported in WordPress by default.
WordPress limits the file types you can upload through your site’s admin — images, videos, documents, audio — for security reasons.
To fix the issue, Please make sure that the below constant is exist in your wp-config.php file. If the constant is not exist, please add it.
define(‘ALLOW_UNFILTERED_UPLOADS’, true);
Please do not forget to remove the code line from the wp-config.php after importing settings.
For more information, I would refer to you https://kinsta.com/knowledgebase/sorry-this-file-type-is-not-permitted-for-security-reasons/
I forgot, I can just copy the text and and paste it.
@dickraney Glad to hear you can import the settings.
