IE11 crashes

Hello,

I’ve been using CF7 for several years now, and never had a problem with it, no matter what browser I was using.

So, now we have a site with forms which all behave strange using IE11. Form submission works nice, validation errors etc., but after succesful submission, clicking any link on the page crashes IE11.

Plugins ‘Dynamic text extension’ and ‘Contact form DB’ are also in use, but disabling them doesn’t make any difference.

I have absolutely no clue where to start debugging. The site in question is built on _s and Foundation3, and using several other plugins for various tasks. Nothing too complex here.

This feels a nasty one, so if there’s someone (a developer?) willing to take a closer look, please ask for a link and wp-user for the site.

Thank you.
