Hi, please let us know your site’s backend login details as private reply so that we can look into the issue (the above login details don’t work)
And where we can check Add Media issue? Do let us know the steps to regenerate the issue. Thanks!
I checked your site tweepp.com using wappalyzer and wordpress is not being detected there. Also, in the site’s page source all default WP paths are being renamed. Please send us screenshots of what is not hidden. And which tool are you using to detect WP?
