I was trying web upgrade and ended up in a blank page. The error file shows the following:

text/x-generic error_log ( ASCII text )

Hi @pattu,

I suspect you’re actually using a version of PHP older than 7.1. The syntax that the error message is complaining about was allowed starting with PHP 7.1. You might want to verify what version of PHP is executing OJS by using a phpinfo script. Sometimes CPanel-based sites can be confusing in this regard.
