Problem to upgrade OJS from to

Hi, I followed the instructions on this page
How to upgrade OJS from version 3 to the latest version » Open Journal Theme to upgrade my site from to
In the end it tells me that has been successfully installed! It doesn’t give me any errors. What am I doing wrong? Is there another procedure that I am not familiar with?
Thanks to who will answer

Hi @Rox_Tul

What is the issue you are dealing with? Have you check you server log error file? Or the browser console for warnings ?


Hello. Thanks for the reply.
In the OJS_new folder I have entered the version but when the upgrade finishes it tells me “Upgrade of OJS to version has completed successfully” (which is the current version) without giving me any error. No errors in the browser console and no errors in the server logs.
So there is no update, it always remains the same version.
What could be the problem?

Hi @Rox_Tul

Could you please check the file in following folder:

And confirm the version of your new install?


Hi @israel.cefrin
in OJS_new folder:

in actual site:

doesn’t want to upgrade and I’m getting a little crazy.


Hi @Rox_Tul

Have you tried to upgrade to an intermediate version as a middle step? E.g. OJS 3.2 ?

Just to ensure that your server is able to upgrade.


Hi israel.cefrin
How can I check if my server is enabled to upgrade?
Is there any parameter on the server that I can check?

Hi @Rox_Tul

To upgrade to the most recent version of OJS you need in your webserver :

OJS 3.2

  • PHP >= 7.2
  • MySQL >= 4.1

OJS 3.3

  • PHP >= 7.3
  • MySQL >= 4.1

You can check your Mysql abd PHP version running from a CLI terminal:
$ mysql --version && php -v

This command should return something like:

mysql  Ver 15.1 Distrib 10.5.9-MariaDB, for osx10.16 (x86_64) using readline 5.1
PHP 7.3.28 (cli) (built: May 13 2021 06:09:33) ( NTS )
