Well, that got the pages working again, but...
One more problem, that did not occur before this blasted update:
When I try to add something to the cart, I get this error:
"Warning: Cannot modify header information - headers already sent by (output started at /home8/starfir3/public_html/products/steel/barb.php:3) in /home8/starfir3/public_html/products/steel/barb.php on line 99"
and a blank page. How do I make the cart active again?
