Project Description:
I have a Business Directory script that I sell and install to customers. I get one or two common errors when I install this script. I usually get 404 error but, if I modify the .htaccess than I get I get a 500 Internal Server Error.
I am still having problems with 404 and 500 internal error on almost every website that I install the script program. I would like to know if there is anything that I can do to avoid this common error. I know every server is different but, there's should be a way to void these errors.

I also think the 404 error could be related to an file but, I do not know to fix it. Please provide me with advice on to deal with this problems.

I cannot pay or seek help for every website that I get these errors. I would like to have this fix for good.
