OCS 500error before any installation

Software Support
1

I search previous Q&As and not find my solution.
centos7 + apache24 + php7 + 5.5.52MariaDB / and also MacOS + php7 +apache24 + mysqlnd 5.0.12
HTTP ERROR 500 when accessing OCS root path. But OJS and OMP successfully lead to installation.

I confirm that config.ini.php exists, file(folder) ownership is proper and set permission 777 to cache folder.

—The following is error log fro httpd, although I am not sure if it will be helpful. Error_log file from virtualhost setting shows nothing.

I try the same OCS packages on CentOS6.8+php5.6+httpd2.2.2.15+MariaDB 10.0.31 success. This should be compatibility issue, isn’t it? I still like to know if OCS can run on latest php.

Hi @shawnhy,

OCS 2.x currently does not run with PHP7.

Thank you so much, asmecher. I think it will be great if this information is mentioned in pkp ocs page.
