Reply To: Fatal error – cal_days_in_month

For the problem with cal_days_in_month() the first google result says:
“To get these functions to work, you have to compile PHP with –enable-calendar”
As you’re the first one with this error it will be a very common setting.

The rest sounds a bit like a your server causes further problems or your theme doesn’t generates the footer correctly. Try to switch to standard theme and maybe even another server to find the problem.
