Where is the bitcoin.conf file located on Electrum? Or how to edit it on Electrum? Was it made through the console?
This is Bitcoin Core's config file, it has nothing to do with Electrum.
Yes, the bitcoin.conf file in the Bitcoin core, server = 1
Did you restart Core? I just enabled it for a different software and it created a .cookie file in my Core directory. See if you find this file there. If you do, maybe you are not using the right path on bwt?
I installed Core in a different drive than my OS and those files could be found in the AppData related to that driver, which in my case is different from OS (E:\Users\username\AppData\Roaming\Bitcoin VS C:\Users\username\AppData\Roaming\Bitcoin), so make sure you are looking at the right place.
