Hi folk, I had installed the LAMP + Ispconfig onto my VPS by following the tutorial at Everything running fine but I prefer to use the Roundcube rather than Squirremail. Glad to know that there was a Roundcube plugin for Ispconfig and I tried it based on the instructions provided at However, when I tested https://184.108.40.206:8080/remote/, nothing on screen just blank page. And, http://220.127.116.11:8081/roundcube/ giving me the following error message: I have the remote user "ispapp1" created and have ticked the options been mentioned in the guideline. What thing I had missed out?? Can anyone help? Thanks.
