After an upgrade on our Linux test server from php 4 to php 5, the server now prompts the user and tries to download the home page when we navigate to test.domain-name.org. If I specifically point to the index file, there are no problems and the page displays fine. The problem only arises if we go to just test.domain-name.org. This generates a download prompt. If I navigate to a page specific url like test.domain-name.org/index.html or test.domain-name.org/index.php, the page loads fine. The Linux guy says he set the server up the same as are other servers which have no issue. Being the php guy, I replied that my code and the mod_rewrite are identical to our other sites which have no issues. I am able to read a phpinfo file. Apache version is 2.2.23. PHP version is 5.3.21. I have read other posts but this issue seems unique from the others. Here is my mod_rewrite code for the home page on my htaccess file:
RewriteRule ^/?(index.html)?$ index.php [L]
