Thanks for your support.
It is my first time using WordPress and I have not installed any 3rd party plugins. And I have added my wp-admin URL, username, and password in private content pls check it.
The name of the theme is Niche market 02 and uses Elementor.
I download the WP reset plugin and install it, but the webpage shows me that I do not have the access to use WP reset.
FTP access is my hosting access?
