Here is what 1&1 support told me to do. It took less then a minute.
? Log into your 1&1 admin panel.
? Under “Domains & Web Space > Webspace > click “Global PHP Version”
? Next to “PHP Version” is a drop down box. Click the arrow and select “php 5” then click “Save”
It was very easy and worked for me. Hope this helps someone.
