Site access problems

Weird that I haven't been able to access the site lately. Hopefully you'll be able to sort it out; I'm at my mother's right now taking a break from helping her with the gardening.

Then I get to go home and continue to fight my own computers - the iMac DV I was using to transfer files from my kaput flat-screen iMac is now not working. My iBook has problems of its own - I had to get a new power cord for it - this is the third one, and they're not cheap.

On the computer here, there are some odd messages on this page, for example:
Warning: Cannot modify header information - headers already sent by (output started at /home/scaryp/public_html/header.php:34) in /home/scaryp/public_html/includes/sessions.php on line 224

and

Warning: Cannot modify header information - headers already sent by (output started at /home/scaryp/public_html/header.php:34) in /home/scaryp/public_html/includes/page_header.php on line 494

There are several others like those, with different lines mentioned.

If I'm still not able to access the site when I get home, I won't be able to see the reply, so e-mail me if you need more info about the problem from my end.

Thanks, hope everybody's having a good holiday weekend.
