Hey guys,
I am really sorry that we missed up this ticket and yes we already added this feature to allow admin to edit the email template file through the backend > Easyblog > E-mail > E-mail template since version 5.1 .
If the editor part is not showing, most likely is because the "Editor - CodeMirror" plugin disabled on the site.
If you guys have any issues, please start a new thread on our forum, and please do not assign the thread category to feature requests if you want to report any issues.
Just for your information, I have locked and marked this thread as resolved to avoid confusion in the future. Please start a new thread if you have any other issues in the future so it will be easier for us to manage your inquiries.
Thanks for understanding.
