[SOLVED] Upgrade to WP 3.9.1 and Atahualpa 3.7.15, page disintegrates in IE

Hi there,
for all those out there who just love Internet Explorer: After I - manually - upgraded both the theme and WP to the latest version, my charity's site doesn't seem to show in IE.
I haven't yet been able to test it myself (no IE), but the descriptions say it shows at first, and then the center column goes blank, as seemingly everything else after a few seconds.

Please help! My URL: www.phaseaustria.org

I did notice that the header image has some problems in Firefox as well, it doesn't seem to rotate through in a stable way, and sometimes goes blank - but I wouldn't really care about that if I didn't have the IE issue ... but it might point you to a solution.

Thank you so much!

First go. To the configure header, center and footer area and press the SAVE button at the bottom and test it again

That's what I did, and now it works fine in Firefox, but not in Internet Explorer - I had a friend test it for me.

I now also have asked for a detailed description: The page displays for about a second or so, and then the center column goes blank, on all pages.

Ok, a friend of mine found a solution:

insert the following in header.php before the </head> tag:

<!--[if lt IE 9]>
<script src="//cdnjs.cloudflare.com/ajax/libs/html5shiv/3.6.2/html5shiv.js"></script>
<script src="//s3.amazonaws.com/nwapi/nwmatcher/nwmatcher-1.2.5-min.js"></script>
<script src="//html5base.googlecode.com/svn-history/r38/trunk/js/selectivizr-1.0.3b.js"></script>
<script src="//cdnjs.cloudflare.com/ajax/libs/respond.js/1.1.0/respond.min.js"></script>
<![endif]-->

and everything works fine ....
Thanks anyway!!!

You might be better off adding that to ATO->Add HTML/CSS Inserts->HTML Inserts: Header
that way you won't have to add it back in the next time you do an update.
