405 Method not Allowed

I am running Apache 1.3.23, with mod_ssl 2.8.7, and PHP 4.2.1 on Solaris 8. When I try to post to a PHP form that is in my htdocs folder, I get the 405 Method not Allowed message for method POST. I have no <LIMIT> directives in my httpd.conf, and I have the 2 AddType application/x-httpd-php lines uncommented in the httpd.conf. I can do a GET of another PHP file so I know that PHP is working. In searching the archives I found some problems if the request is via HTTPS but this is an HTTP request that is failing. I have tested the PHP forms on another webserver running the same version of Apache, without mod_ssl and with a few different PHP options and they work fine. Thanks in advance for any input you may have. ------ Kevin Van Der Hart Systems Administrator Vermeer Mfg Co
