Problem upgrading from 2.4.8 to 3.0.2

[ctgraham]

Are you trying to run the upgrade more than once? If so, you must restore the database and files to 2.4.8 before trying the upgrade again:

UPGRADING OJS 3.0.0 A database error has occurred: Duplicate entry 'tinymceplugin-0-enabled' for key 'plugin_settings_pkey'

@asmecher Exacly! I performed the upgrade, and sth did not work so I re run this and got this error. To resolve this I had to mysql> DROP DATABASE databsasename; mysql> CREATE DATABASE databasename; mysql> use databasename; mysql> databsasename < bacupfile.sql; I hope this will save people some time
