I have fixed this issue by doing the following:
1. clearing the sites/default/files/civicrm/templates_c
2. Corrected Resource URL
3. and also go to administer - system settings - cleanup caches & Reset paths
Do you have multi-lingual enabled? than try to rebuild the views to see if it resolves your problem
Missing column 'frontend_title' in ''civicrm_uf_field_de_DE" after upgrading to 5.1.2
Do you have DB logging enabled? than disabled and enable back again.
Else can you check the CiviCRM log/watchdog to get more details of DB error?
