I'm working on a new install.

The Events/Dashboard menu choice generates a screen with the following error:

Sorry, due to an error, we are unable to fulfill your request at the moment. You may want to contact your administrator or service provider with more details about what action you were performing when this occurred. DB Error: unknown error Return to home page.

There's nothing in the DB log.

I tried the Settings/Cleanup Caches and Update Paths/ panel doing both Cleanup Caches and Reset Paths, but to no avail.

I'm stumped.

  • Can you mention the CiviCRM version and cms you using? Jun 20, 2018 at 20:36
  • CiviCRM 5.0.2, Drupal 7x. Jun 20, 2018 at 20:59
  • Can you enable debugging options under Administer->System Settings-> Debugging and Error Handling And then goto your CMS root -> sites/default/files/civicrm/configandlog and find the most recently modified file, open it, delete the content and save. Do the same for your php/server error log Go back to the error page, then open those 2 log files back and post what's displayed there Also if you enable backtracing it will show further details on the error screen Jun 20, 2018 at 21:34

This was a core bug and was fixed at 5.1.0. You can either apply the patch from here or Upgrade CiviCRM to 5.2.2.
