Hi all, I've searched on Forum but I didn't found a solution. I've an issue with Munin configured on ISPConfig 3. When I try to access Munin through "ISPConfig -> Monitor -> Show Munin" it show a blank page, so I try to check errors on loading page with Google Chrome Dev Console and it shown following: "Refused to display 'https:// <user> : <password>@<domain>/monitoring/' in a frame because it set 'X-Frame-Options' to 'SAMEORIGIN'." I've configured SSL with StartSSL Class 1 Cert and Security Headers on Apache, but when ISPConfig 3 try to access Munin page through iframe, rightly X-Frame-Options refuse to show page because ISPConfig 3 prepend user and password and cannot matches "SAMEORIGIN" option. Below some Informations about my Server/Softwares: - Ubuntu 14.04.4 LTS Server; - ISPConfig 22.214.171.124p9; - Apache 2.4.20 - Munin v2.0.19-3 It's an ISPConfig 3 problem with Munin and X-Frame-Options enabled or other? May someone help me? Thanks in advance.
