I am trying upgrade ojs 2.4 to 3.0.2. I met too muct problems.
First, Duplicate entry ‘defaultthemeplugin-0-enabled’ for key 'plugin_settings_pkey’
problem. I solved this problem by restoring my database from backup. After that
i faced with A database error has occurred: ALTER TABLE causes auto_increment resequencing, resulting in duplicate entry ‘2147483647’ for key ‘PRIMARY’ problem. also I have solved that problem by changing values of the tables on this DB.
later, I came across the problem of error 500. I corrected the error in php.ini file and this problem has been solved. bu now “405 not allowed /nginx” problem was appeared. Is there any one help me.
That last message (
405 not allowed /nginx) isn’t coming from OJS. I’d suggest looking in the log again to see if there’s another message that might be appearing there.
