I Can install OJS 3.X on Ubuntu 16.04 PHP7

Greetings from Ethiopia,

I was using OJS since 2010, Currently i wan to migrate all hosted services to New Ubuntu Server, 16.04
how ever I couldn’t use OJS on this server, may be PHP 7 compatibility problem.

Could yo please help me on how to fix this issue?


Have you tried updating via sudo apt-get update in a shell? You can also use which php to see where your PHP is and then compare with your installation to see if the pointers are correct.


Also see here for another possibility:

What version of OJS3 you are using?
OJS 3.0.2 works perfectly on Ubuntu16.04 with latest PHP. I recently updated the system and all soft for latest versions on our production site.

You need to check your PHP logs for errors. Look for fatal errors.

how to fatal error fixed in ubuntu 16.04 version

Hi @first,

OJS 3+ should work without problems on Ubuntu 16.04. Have you encountered with the specific issue?

I see that you have already asked the question on a different thread: Fatal error: Uncaught Error: Call to undefined function xml_parser_create()
