Stylesheets not fully loading

[ericpedia]

I am experiencing frequent problems with WP-Sass stylesheets not fully loading.

Here's what happens: I go to some page on my website, and the page will load with only some (or barely any) CSS styles applied. If I visit http://.../path/to/mystylesheet.css, it will show the full stylesheet just fine; but if I go into Inspector/Firebug and look the loaded Resources, it will show an incomplete version of the stylesheet—it will cut off somewhere randomly, in the middle of a line.

When this happens has no relation to when I have edited the SASS files.

Some notes:

• I am not using any caching plugins.
• The site I am working on gets ≈5,000 page views a day (don't know if this could be relevant, with multiple people accessing things at the same time)
• I am on a VPS with generous PHP limits. Still, I would say the site is a bit slow.

Any idea what could be going on?

Hi, if its cutting out halfway through a line then it might hitting a PHP
error. My next step would be to look at the PHP error log for timeouts or
wp-sass problems.

Would you say it's a big stylesheet?

With LESS I've had this issue with a bad var or microsoft mixins. You should investigate to see where it cuts off and see if you're using a mixin, variable or otherwise at that location.

@sanchothefat There are two stylesheets—one is 41kb, and the other is 24kb. They both seem to have the problem.

As it turns out, there are a bunch of wp-sass-related errors in /usr/local/apache/logs/error_log:

[...10:39:18] [warn]  ... ] mod_fcgid: read data timeout in 40 seconds, referer: .../wp-sass-cache/sass_main.css?ver=3.5.1

There is also a recurring error that I'm guessing is not related, in the error_log file in my theme folder:

[14-Apr-2013 17:07:19 UTC] PHP Fatal error:  Call to undefined function get_header() in /mytheme/index.php on line 17

@noeltock Where it cuts out doesn't seem to be related to the actual sass/scss code. It will cut off literally in the middle of a word, and then on refresh it will load fine.

[roborourke]

Thanks, that should help narrow it down.

The first fatal error looks like someone or some script trying to load your
theme files directly. A check at the top of the theme files for ABSPATH
being defined will stop those.
