Hi! I have installed Limesurvey on a Linux Server (Ubuntu 11, Apache2, PHP5) and everything works fine except email. I am using a gmail account (the email settings are fine. i have tested them with other Limesurvey installations).
When i try to send an email with "Send invitation email to this entry", i can move to the next page where you can edit the e-mail text and when i press "Send invitations" button i get an empty/blank/white page. Emails are never send!
I think that is something wrong with PHP. Maybe SSL module is not loaded... I run phpinfo and i can see that openssl module is loaded.
I move files and database to another (desktop) PC and email works fine!!!
Note: I have made some modifications to Limesurvey code but i don't think this is the problem. The same modified code has no problem with emails when i use it on my desktop.
