I just made an update of ISPconfig (from 2.2.12 to 2.2.21). Now I encounter quite a strange problem with Firefox on Linux (not with other browsers, as well as FF on Windows): If I request the entrypage of my website (http://www.heiner-lamprecht.net/)
, Firefox offers me to save the page to disk, and the php source is saved. Other browsers can show the real page.
The problem only
effects the entry-page. If I enter the URL of some other php-page, it works.
Honestly, I don't understand this issue. I know, it's strange but maybe someone has an idea, what to do.
