If I turn on aggregate css in my performance config and then load my site in IE7, the browser crashes. Any ideas why that might be?

Thanks, Paul

  • Can you expound upon "the browser crashes"? Does the application literally stop responding, or is the web page just rendered incorrectly? Are there any error messages in your logs (Drupal, PHP, apache, etc.)?

  • Browser crashes means IE7 closes and there is a dialog saying "Internet Explorer has a problem and needs to close" May 3, 2012 at 8:11

There is a size limit of 300kb per file and a limit of 32 files.
