Hi @Lemper.Abon,

PHP 7.0 isn’t supported by OJS 3.2.1-2. The requirement is PHP 7.2+

Hi @Lemper.Abon,

Did you unpack the OJS 3.x code over top of the OJS 2.x code? If so, you’ll have mixed the two codebases together, which can cause problems like this. It’s better to start with a clean OJS installation directory and only bring in the pieces you need. See the “Full Package” upgrade instructions in docs/README.md.
