problems with upgrade on multilingual site (in this case 4.7.31 to 5.3.1)
There is some issue in rebuilding schema for multilingual instance when upgraded to 5.x version. For the moment you will need to manually rebuild the schema using drush or civi api. 

Details to rebuild schema can be found at Multilingual instances show &#39;no such field&#39; errors after update
