Hi, from log its seems that ManiacCallouts cause problem - maybe its whole plugin problem, maybe specific callout - this you would need to test by yourself. But if you don't want then just simply remove this plugin and should be ok.
Also I would suggest to remove:
Better EMS - outdated
Keep Calm - outdated
Police SmartRadio - outdated + you already have GrammarPolice
And update
jm-callouts - new patch released few hours ago
