This is usually caused because you do not have index.php set as the default document for the directory in IIS.

Or if you are using IIS5.0 or lower (Windows 2000)
This version has a bug who doesn't accept a action="./" like set in the login.html file.
To correct this, replace everywhere action="./" by action="./index.php"

same problem here

nginx 1.14.0 & php7.0 & rc 1.3.6

only happens with roundcube

nginx error: "2018/05/17 03:11:38 [error] 30583#0: *7 flv live: HTTP method was not "GET" or "HEAD", client: 91.XX.XX.XX, server: webmail.url.tld, request: "POST /?_task=login HTTP/1.1", host: "webmail.url.tld", referrer: "h$"

so i think i need to change ./ to ./index.php - but i dont know where
or where to set index.php as defalt
