Hello,
Thanks for your Patience!
This is not an Issue with the Canvas Template but an Issue with IE11 Compatibility Mode. IE11's Compatibility mode degrades the Browser's CSS/JS Support. So you cannot expect a Template using the Latest Versions of all Plugins, Resources and Coding Practices to run smoothly.
To fix this issue, simply add the following code in your Document's <head>:
or Add the following code in your .htaccess File:
Header set X-UA-Compatible "IE=edge"
# `mod_headers` cannot match based on the content-type, however,
# the `X-UA-Compatible` response header should be send only for
# HTML documents and not for the other resources.
Header unset X-UA-Compatible
This should fix your issue automatically. Hope this Helps!
