Please i need help in configuring this Oscommerce problem on www.absinternational.com

Most times the Index page works, and sometimes i doesn't.

I need a hand out of the problem

I am familiarized with osCommerce installation myself. Can you tell me what happen when you something change on osCommerce that causes error picture mentioned you attached here?

Sometimes you might be missed PHP syntax or forgot close tag at the end of the page you modified for oscommerce or forgot to include required pages to upload your hosting server. That cause error.

Be sure you should also include the english.php on the includes/language folder that is MISSING. You see that the blue color stated 'includes/languages/.php' is not right file directory.

CORRECTION: 'includes/languages/english.php'

Be sure you did UPLOAD WHOLE osCommerce file exactly like this picture at below(I cannot list everything but index folder, admin folder and includes folder are MOST IMPORTANT when it comes to modification pages):

Do not leave out missing folders/PHP pages that cause your osCommerce site ERROR!
