I am trying to set up a masternode. The whole procedure worked without a problem up until step 10. After I edited the masternode.conf file to include the specific info for my masternode I restarted the Kore wallet and received the following error message:
Enabling masternode support requires turning on transaction indexing. Please add txindex=1 to your configuration and start with -reindex.

I am not sure how to fix this. Could someone please point me in the right direction?

Thanks.
