Http Error 500 - PHP 7.1

Hello, its my first time here, in this forum.
I have searched some topic like mine, but I didnt find. If my topic is wrong, please tell me.

I had ojs 3.0.0 working fine in PHP 5.6. But my host ( has migrated its PHP version to at least 7.1. And my journal is not working anymore (

I have read that this version of OJS works fine with this PHP version, but is not working for me.

Somebody has some idea?

Thank you very much.


You must change the database driver, from mysql to mysqli in file
