<p>It seem like you tried to run fallbackfee in the terminal ? fallbackfee is a configuration option and should be put inside a bitcoin.conf file, if you dont have this file on your bitcoin directory you can create it: <a href="https://en.bitcoin.it/wiki/Running_Bitcoin#Bitcoin.conf_Configuration_File" rel="nofollow noreferrer">https://en.bitcoin.it/wiki/Running_Bitcoin#Bitcoin.conf_Configuration_File</a></p>

<p>Then add your <code>fallbackfee=someValue</code> (without the -) inside your bitcoin.conf file on a new line then restart your bitcoin client and try your command again.</p>

<p>Another option that works for me is to call the <code>settxfee</code> with amount before calling <code>sendtoaddress</code>.</p>

<p>I'm trying to send some bitcoins using bitcoin-cli API, but bitcoin core tells me that Fallbackfee is disabled. How can I set a value for fallbackfee? 
I've tried to specify it like
 <em>bitcoin-cli sendtoaddress -fallbackfee=someValue</em> but it didn't work.
 I've also set <strong>true</strong> for <em>substractfeefromamount</em> and <strong>false</strong> for <em>replaceable</em></p>
