We’ve seen a few reports of issues like this and in many cases its due to a corrupt setting. Please try going through the steps below!

1. Run these commands in-game in chat to disable server side syncs then log out:
   /console synchronizeConfig 0
   /console synchronizeSettings 0
2. Delete your character folder:
   World of Warcraft_retail_\WTF\Account{Account ID}{Realm}{Character Name}
3. Log back in and the issue should be resolved. If so you can re-enable the server side syncs:
   /console synchronizeConfig 1
   /console synchronizeSettings 1

Try that fix for Quest log issue.
