oh your log shows it's still loading messages. If this is really the end of actual log it means that it's taking a long time loading your messages. One issue with all current wazapp versions is loading all messages during startup. So it looks like it's taking too long in your case. A quick solution is to delete your db "rm -r /home/user/.wazapp". This will however delete all your chat history but I'm sure it would at least get wazapp to work again. To keep your history I suggest you copy this folder somewhere before deleting it. I'll try to get partial loading of messages to be in next update which should solve your problem. So if this happens, you could restore that folder back after update and it should run normally.
