Hey guys. just wanted to share. i just got it to work just now.
here is what i do:
- go to AutoSSL (FREE) tab
- select the desired username
- then you see the error right? keep calm. and inspect element on the select input and edit as html
- you will now edit the html using your domain name in the value of the select
- then inspect element on the button as well. remove class disabled and remove attribute disabled="disabled" using your inspect element edit as html
so, pretty much working actually. its just a minor bug on the
ajax of the cwp panel. LE itself works.
inspect element. edit the html directly like this:

for the button. remove the disabled attribute and class

yeah. i do this and the ssl installed perfectly.
hope this helps!

DISCLAIMER: this is for domain without any ssl only
