###my bitcoin core say "syncing headers" and it totally stopped downloading blocks for more than 20 hours from then. this happened after 1/8 hard fork and after i set up the bitcoin ABC wallet 0.14.6, which i have removed. i tried many things and really confused now. all i want is to claim my bitcoin cash and move it to a market. please help me with this big thanks!

Same problem here, I ran Bitcoin ABC yesterday. It did share the same Blockchain Data as Bitcoin Core. I could not run both at the same time since some directory gets taken exclusively by one or the other app. Today Bitcoin Core ist stalled at 99.89% and block 479758. How do I "unblock" my BTC Blockchain? Or redownload? Thank you.
You cannot have different currencies' blockchains be stored in the same location; the result is likely corruption both directions. You can always run with -reindex to wipe the database and just process the blocks you already have again.
8-O OMG ... THE man with the most commits on Core is answering... Thank you Peter! If you could just explain to a noob on how to run the -reindex command on a Mac? Do I do that while running the GUI somehow in the console? (tried verifychain...) Or do I start a Terminal, navigate to some place, launch bitcoind...? BTW. I saw a picture of you and some UASF-Supporters which lead me to believe you are now in SF. If I remember right you lived in Zurich? I live in Zurich and always wandered if you are around... Viele Dank für Dini Hilf! Don
@DonDerossi I don't have a mac, so use at your own risk: There should be an executable file at /Applications/Bitcoin-Qt.app/Contents/MacOS/Bitcoin-Qt. So just call that in the command line and append -reindex once for this call.
/Applications/Bitcoin-Qt.app/Contents/MacOS/Bitcoin-Qt -reindex
I also started getting this error. I have never used the ABC client.
Update:
Found this in the debug log:

I see this on a clean VM that just runs bitcoin-ABC. It just stops downloading blocks. Killing and restarting works to continue the download but then it gets stuck again requiring a further restart. I have not seen it on a clean VM that is just running core - but I do not rule it out.
SOLVED!
Thank you very much Marco Falke!
/Applications/Bitcoin-Qt.app/Contents/MacOS/Bitcoin-Qt -reindex is the exact instruction for using in the Terminal on a Mac.
The reindexing took about 2.5 days on my 3 year old MacBook Pro Retina but now everything is back to normal.
Thank you Core Devs! Thank you Core Maintainers! Go SegWit! And sorry for running this Bitcoin ABC garbage.
