Our journal disappeared from the website and we are trying to reinstall it. We have a backup of database but when we try using it we receive a message that it is running using the old version of php5.
The challenge we are facing is that on trying to input the data, the message says not compatible with the new version of php7 and also other error messages.
The Application Version is OJS 3.0.1
Kindly advise on how this can be resolved.
