I used OJS 3.1.1. in this last one year. Today I try to Upgrade to 3.1.4. as suggesting by PKP. I was following all instructions and placing the debug in config.inc.php. I’m shocked it is not working although the OJS said its successful to Upgrade. Even PKP ask me to re-registering like a new user. I’m really regret was upgrade because all of my works disappeared, including all of articles from authors that published. Please help me, how am I must do? May I bring back the old version? Look at my website now https://journal.riksawan.com. It’s a horrible day for me. I can’t imagine if I must make it all from the beginning. Please help!!!
