DBALException: .... and PDOException:
  • I tried to install newscoop 4.3 in VPS, and got these errors:
    "DBALException: An
    exception occurred while executing 'INSERT INTO SystemPreferences
    (`varname`, `value`, `last_modified`) VALUES ('installation_id', ?,
    NOW())' with params ["d45727efb1a36c75a915f86bab936d3b62833a11"]:


    SQLSTATE[23000]: Integrity constraint violation: 1062 Duplicate entry 'installation_id' for key 'varname'"

    Another message:

    "PDOException: SQLSTATE[23000]: Integrity constraint violation: 1062 Duplicate entry 'installation_id' for key 'varname'"

    Please tell me how to fix this? Thanks.
