I have just updated CiviCRM under Joomla! from 4.7.6 to 5.10.0. The upgrade went well, with no issues. I have following the instructions on the page "Upgrading CiviCRM for Joomla". I can use CiviCRM except whenever i access any report menu i get :
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
Items on here say to look in the ConfigAndLog file which i think for Joomla should be at administrator/components/com_civicrm/civicrm but i do not see it there.
Anyone have any suggestions on how this can be resolved?
