Title: Bitcoin Core - can't open bitcoin.conf
Post by: BlackHatCoiner on July 14, 2020, 01:39:43 PM
When I click "Open Configuration File" in settings of bitcoin core I get these:

If I go to %AppData% -> Bitcoin -> bitcoin.conf
I get an empty file:

I remember I had made the bitcoin core installation some months ago, and I successfully changed things inside the bitcoin.conf, like for changing to testnet/regnet.

Any help? What do I do now?

Either you hadn't actually changed the bitcoin.conf file, or it got lost. Bitcoin Core has either found an empty bitcoin.conf or did not find one at all.

So how do I remake it? Can I copy it from someone else?

Here's a nice WebUI[1] if you don't want to do it yourself. If you want, just create a new file (using notepad) and name it bitcoin.conf, making sure the extension is .conf. You can edit it using any text editor.

Additional for this if you are manually making a bitcoin.conf file you can copy the default sample of bitcoin.conf from the link below.

- https://github.com/bitcoin/bitcoin/blob/master/share/examples/bitcoin.conf

Copy all text inside from line 1 to 171 and paste it to the bitcoin.conf file you created.

For reference: I've successfully reproduced the issue by setting the bitcoin.conf file as "read-only":

If it's missing, core will make one, once he clicked the "open config file" button without errors; if the whole folder was set to read-only (or a permission issue), core fails to launch at all.
So BlackHatCoiner might have set it to read-only for some reason or the file became inaccessible.
