( ojs-3.3.0-8 ) PHP Fatal error: Uncaught PDOException: SQLSTATE[23000]: Integrity constraint violation: 1062 Duplicate entry

Hello @henriqueramos ,

I actually fortunately got help from other related issue that also resolved this issue of http error :smiley: So thank you so much anyhow. They are different error message but essentially due to a bad apache redirect configuration. The error LOG I gave you probably has been the wrong error.

BTW, emptying the “sessions” table does not have negative effect, it will be regenerated.

Best,

Dung.
