I updated my wallet and it would not sync. I followed these instructions:
Windows:
File Explorer: %appdata%/BiblePayCore
Delete blocks and chainstate folders, delete banlist, fee_estimates, governance, mncache, netfulfiled and peers
In Wallet do Tools >> Wallet Repair >> Rebuild index
I have done that twice and I still do not have transactions coming through ,and the last transaction it shows is from 4/12/2018
Can you find any peers? You only need to run the .exe really. No need for the other steps unless you run into problems.
Maybe just give it some time?
