Dash Application fails to load with IE Compatibility View

I am hosting a Dash application internal to my organization and one of our users reported a page load error on IE 11. Investigation revealed that the user had our internal website domain listed in IE's Compatibility View settings. I confirmed on my own machine that adding the domain to compatibility view reproduced the error and removing the domain from compatibility view immediately allowed the page to load.

Is there a known workaround in Dash so that pages will load even if the domain is in compatibility view?

Thanks for reporting @drRussClay ! This was last discussed in #275, and we decided to add the tag. In code, it's here:

dash/dash/dash.py

Lines 378 to 394 in 7361db5

    
           def _generate_meta_html(self): 
        
               has_ie_compat = any( 
        
                   x.get('http-equiv', '') == 'X-UA-Compatible' 
        
                   for x in self._meta_tags) 
        
               has_charset = any('charset' in x for x in self._meta_tags) 
        
               tags = [] 
        
               if not has_ie_compat: 
        
                   tags.append('<meta equiv="X-UA-Compatible" content="IE=edge">') 
        
               if not has_charset: 
        
                   tags.append('<meta charset="UTF-8"/>') 
        
               tags = tags + [ 
        
                   _format_tag('meta', x, opened=True) for x in self._meta_tags 
        
               ] 
        
               return '\n      '.join(tags)

Could you confirm that you are using the latest version of Dash that has these changes? Or, are these changes causing the new issues?

I'm using version 0.21.0, and since this fix is pretty new, I'm guessing I don't have it included. I will update and test to see if it fixes the problem. Thanks!

Thanks! You can see the list of changes in the changelog here: https://github.com/plotly/dash/blob/master/CHANGELOG.md. It looks like it's part of 0.23.1

I made the update but it doesn't solve the problem. If I add the website domain to compatibility view settings, my application will not load. I'm on Dash version 0.25.1. I also tried updating dash core components, dash html components, and dash renderer to the most current versions but it did not fix the issue. Any suggestions? I am serving the application via IIS; could that have something to do with it?

I'm having the same issue, so a fix would be great!

@drRussClay - there was a bug in the meta tag definition that was fixed in v0.28.3
