We have worked long and hard on this site for our client as a pro bono project. Now, soon before launch, it is running into issues with load time. In every other browser it works great, about 1-2 seconds, but IE7 and IE8 take 25 - 40 SECONDS to load the site.
Here is the waterfall view of your site using IE7 from London server from webpagetest.org
There are lot's of 404 coming from
these missing hIEfix.png are coming from the stylesheet
where you have lot's of IE explicit css like this line:
Please try to remove "AlphaImageLoader" in your css : http://salvationarmynorth.org/wp-content/themes/salvationarmy/style.css
IE's AlphaImageLoader blocks rendering and increases page load times.
hope this help :-)
It's a strange problem. As I guess it's coming from the conditional coments. Using debuger tool in IETester, the html tag interpreted by IE7 is:
<HTML class="no-js lt-ie9 lt-ie8 wf-adobejensonpro-i7-active wf-adobejensonpro-i4-active wf-adobejensonpro-n4-active wf-adobejensonpro-n7-active wf-adobejensonproi7-i7-active wf-adobejensonproi4-i4-active wf-adobejensonpron4-n4-active wf-adobejensonpron7-n7-active wf-trajanpro3-n4-active wf-trajanpro3-n6-active wf-trajanpro3n4-n4-active wf-trajanpro3n6-n6-active wf-trajanpro3n3-n3-active wf-active" lang=en sizcache015729147214778233="16" sizset="3">
the one interpreted by IE8 is:
<HTML lang=en class="no-js lt-ie9 wf-adobejensonpro-i7-active wf-adobejensonpro-i4-active wf-adobejensonpro-n4-active wf-adobejensonpro-n7-active wf-adobejensonproi7-i7-active wf-adobejensonproi4-i4-active wf-adobejensonpron4-n4-active wf-adobejensonpron7-n7-active wf-trajanpro3-n4-active wf-trajanpro3-n6-active wf-trajanpro3n4-n4-active wf-trajanpro3n6-n6-active wf-trajanpro3n3-n3-active wf-active">
and interpreted by IE9 is:
<html lang="en" class="no-js wf-adobejensonpro-i7-active wf-adobejensonpro-i4-active wf-adobejensonpro-n4-active wf-adobejensonpro-n7-active wf-trajanpro3-n4-active wf-trajanpro3-n6-active wf-trajanpro3-n3-active wf-active"><!--<![endif]-->
in IE9 interpreted code I see <!--<![endif]--> added to html tag, it's the diference between IE7 and IE8, that's why I suggest to verify the conditional comments code, maybe the problem comes from there.
