Multibit 0.5.17
You can clear all of the unconfirmed transactions, however instructions for doing so depends on whether you are using MultiBit HD or MultiBit Classic. Once you clear all of the unconfirmed transactions out of your wallet, you can resend the transactions, but this time with a sufficient fee.
Hi, I have this same problem. I have multibit HD 0.4.1, and I want to clear my unconfirmed transaction to add a larger fee, but the instructions on their website aren't available on my version. On the website it say to go to tools, and then click on the 'clear transactions' icon, whcih isn't there. Do you know another way? Thanks in advance..
