php5 config?

cbrace · #1 September 21st, 2012, 11:39

Hi all,

Here is a tricky one:

(disclaimer: I know nothing of PHP)

I am using a blank Joomla template to create a new template for a www/joomla25 site. This template uses a file called css/template.css.php to load the template's CSS files and send them as one long compacted string (minimized) (code below).

On my FreeBSD server (PHP 5.3.13) template.css.php returns garbage:

http://wfbrace.com:8000/templates/wf...ss.php?b=0&v=1

Wit the same template installed for test purposes on a production server running some Linux (PHP 5.3.10), hosted at Byte.nl, template.css.php returns the CSS, in MIN form:

https://www.sense-online.nl/template...ss.php?b=0&v=1

What could be going wrong on my FreeBSD server? A wrong PHP setting? A missing php5 module?

Thanks.

If I request the file by hand with a simple HTTP request I get it fine, but in a web browser it's messed up.

I'm wondering if you're gzipping the data twice. My handmade request had no 'Accept-Encoding' header, so the server should not have tried to gzip the content, but it would with the web browser.

Can you try removing the following line:

Code:

ob_start ("ob_gzhandler");

I have never used this, I usually just configure an output filter via the web server to compress all relevant mime types. It's possible you are passing the content through ob_gzhandler in PHP to compress the data, and then the web server is configured to compress any text/css data, so is doing it again.

Yep, that fixed it. Thanks! I'll pass this info on to the author of the template.
