It basically denies remote requests to our server. You should talk to your hosting provider to either deactivate this module or let them add aamplugin. com domain to the whitelist. * Meantime try to install extension manually. Check this article [https://aamplugin.com/help/how-to-install-aam-extension-manually](https://aamplugin.com/help/how-to-install-aam-extension-manually) * Thank you, Vasyl * Thread Starter [edemir206](https://wordpress.org/support/users/edemir206/) * (@edemir206) * [8 years, 6 months ago](https://wordpress.org/support/topic/problem-installing-multisite-support/#post-9756143) * Hi, * I tried installing uploading trhough FTP but it didn’t work either, the button for installing multisite extension is still green and site list is not activated. * I have root access to the webserver I can confirm it does not have mod_security enabled or even installed, also all the permissions are correct for my server/ host account. * Do you have any idea of what can be the issue ?
