Since upgrading to v2.4.0.beta2 +229 just recently, a number of our users are reporting the site does not load on Internet Explorer 11.557 anymore.
Is IE supported at all these days? 
I believe we already rolled out fixes so be sure to be on latest.
Thanks @codinghorror just bumped to v2.4.0.beta2 +238 and it’s all working on IE again 
I guess it was this one
