Hey there,

In Windows 10, Microsoft Edge not login in easysocial,
Can someone help me solve?

It seems like you are not alone, you can take a look of their support page -> http://answers.microsoft.com/en-us/windows/forum/apps_windows_10-msedge/cant-log-in-to-any-websites-on-edge-browser/4b9c8296-0e4c-416e-8ccb-66a843cd6a69?auth=1

First, I've tried to login in your site using Chrome browser and Edge browser, the login work with Chrome browser but I was unable to login in your site through Edge browser.

Then I do some research from Google and see is it can found out some solution for that, base on their information, most of them also talk about the cookies data from browser, so this is what I try in your site :

1. Remove your Cookie Domain/Cookie Path from Joomla backend > system > global configuration
2. Clear history/data/cookies from my Edge browser
You can take a look this instruction how to clear it -> https://www.wiknix.com/how-to-clear-cache-and-cookies-in-microsoft-edge-browser/
3. Then close your Edge browser and open again
4. I can able to login in your site through Edge browser now.

Perhaps you can give it a try and see how it goes.
