What do I do?
If .htaccess needs to be altered, what do I put, plus which .htaccess.?
You have cache/.htaccess which says deny from all. I changed to allow form all, but not work
Then there is .htaccess which has RewriteBase. I don't know what to put.

Hi and welcome,
You have PHP 5 or PHP 4 ?

You have put a CHOMOD 777 on folder cache and compiled with your ftp software ?
