PHP code sometimes not interpreted

[Anon]

Hi all,
I'm hosting a site at an ISP. The php code I'm using is sometimes not interpreted, if I open a page I see php-sourcecode. If I press the refresh-button of my browser 2 or 3 times sometimes the problem is gone, sometimes not. I checked my code on other servers, so this is probably not an issue. Even a simple phpinfo is sometimes not interpreted. The provider says its my code thats buggy, but what about the phpinfo that doesn't work ?

PHP will not be interpretted if the addType application/x-httpd-php is not added to your apache config.

I've never heard of this type of problem...but if your host is running load balancing and your site is actually mirrored across their network, then I could see that it would be possible that not all servers have the same apache configs for your vhost.

That or PHP is not loading properly at runtime...

Could be a lot of little things but all fingers point to apache.
Check your logfiles.
