Cannot run cgi after update 4.3.1

Hi Web Master I just get update to PHP4.3.1 from PHP4.1.2 on RedHat7.3 with Apache1.2.23 and Mysql 3.23.49. However, after install PHP 4.3.1 followed the instruction, some function in my web page is not funcationing. I have a php-cgi script called 'category.php?cate=concert' for example. I found that the program didn't reconge the parameter. But WHen I was using PHP4.1.2. That is working. Is there any procedure I did wrong when I install. I did the installed is : ../configure --with-mysql --with-apxs make make install I know there are many options I can type (e.g. --enable-force-cgi-redirect --with-???) So, What can I do so that I can use back the cgi like before? Moreover, I want to use MHASH function in PHP also. I try to install and compile in PHP. BUt is not work at all. WHat can I do? Regards Thanks so much your help Rex
