Server error with php5 extension.
 

Downloaded latest version of vBulletin with the PHP5 extension, uploaded files to server in same location as prior files, update was successful but when I clicked on the admin login window an internal server error appears. Prior files had php extension.

Any suggestions as to what I did wrong? Is it possible to upgrade from php to php5 extension in order to use PHP5?

Thanks.

You should continue to use the .php extension. Please re-download vBulletin and upload the regular files and rerun upgrade.php.

You should only use the .php5 version if your server is configured to accept that extension!

The reason I tried the php5 extension was that vBulletin won't recognize the PHP version 5.x on the server. It only recognizes the PHP 4.x version.

I added AddType application/x-httpd-php5 .php to the .htaccess file, which joomla recognizes it and uses it, but vBulletin causes an Internal Server Error.

I've temporarily closed my forum board while I try to get vB running on PHP 5.x. (UPdate: forum now open but still running on PHP 4.x)

I've also tried AddHandler application/x-httpd-php5 .php in .htaccess. Same Internal Server Error with vB but joomla works fine. Go figure.

I've been driving my hosting company nuts the past three days trying everything to get vBulletin to recognize and use the PHP 5.x on their servers. And they have been hugely patient with me.

Any suggestions most appreciated.
