Fron 2.4.8 to 2.4.8-5

Hi @lacris,

Those warnings are cosmetic and shouldn’t cause you any problems – just make sure they are directed to the log file rather than the web browser.

Hi asmecher!

I don´t know how to do that. Coukd you please tell me how to redirect that to log web server?

In my I have
deprecation_warnings = Off
But it seems it ignores me.

Thank you!!

Hi @lacris,

This will be your PHP configuration file, rather than your OJS configuration. See: Turning off Deprecation warnings in PHP.ini file WAMP - Stack Overflow

If possible, make sure to restart your web server process; that’s required on some servers in order to have php.ini changes take effect.

Hello again,

I think that my php.ini is right but I´m going to check it again more carefully.
Thanks again.

Hi again,

I´m lost.

I’ve tried putting different options but those two lines keep coming out.
;error_reporting = E_ALL & ~E_DEPRECATED & ~E_STRICT & ~E_NOTICE
;error_reporting = E_ALL & ~E_DEPRECATED & ~E_STRICT
error_reporting = E_ALL & ~E_DEPRECATED → this is the old server option (ojs 2.4.8 with php 5.3)

any idea?
Thanks a lot!

I would expect that line to work.

Double check that the PHP interpreter in use for your webserver is connected to the php.ini which you are editing, and that the error_reporting setting is not being overriden by another ini file or PHP directive. Your system administrator or hosting provider would be able to assist in verifying that.

If you are comfortable adding a new PHP file to your system, a quick way to test this would be to add one with just the content of:

<?php phpinfo(); ?>

Visiting this php file in your webbrowser will share a large amount of (potentially sensitive) information about your PHP install. One line will describe what the error_reporting variable defaults to, and what the effective value is after all processing.

The phpinfo() confirms that the file that is being used is /etc/php.ini and that is where I am doing these tests with the different options to show the errors (error_reporting).
I will try the first option again [ error_reporting = E_ALL & ~E_DEPRECATED & ~E_STRICT & ~E_NOTICE], reload apache and load ojs to see if with a new day, it works … (ha, ha).



Hello again,

I have done what I said above but nothing has changed.

The same two lines appear on all OJS pages, from the cover page to the detail of an article (*)

Deprecated : Non-static method PKPApplication::defineExposedConstant() should not be called statically in /web/sp/ojs-2.4.8-5/lib/pkp/classes/core/ on line 545

Deprecated : Non-static method PKPApplication::getExposedConstants() should not be called statically in /web/sp/ojs-2.4.8-5/lib/pkp/classes/core/ on line 513

I don’t know PHP but could I try to modify those two lines to avoid those messages? It is easy?

(*) Before modifying php.ini, many warning lines appear. Now I only have two, so something has been done thanks to modifying the php.ini error_reporting but I can’t remove all warnings. It’s very strange!

What is the Local Value and the Master Value for “error_reporting” in your phpinfo() output?

Hi ctgraham,

It has the same value:

That is the value for E_ALL & ~E_DEPRECATED & ~E_STRICT & ~E_NOTICE, so your configuration is working.

I bet this is a E_USER_DEPRECATED level message. Try:


Good morning ctgraham,

I tried the new log parameter but everything remains the same.
If you can think of anything else I can try, let me know.

Thank you!

Hello again,

I have been adding new parameters but I still see the same two warning lines
error_reporting = E_ALL & ~E_DEPRECATED & ~E_STRICT & ~E_NOTICE & ~E_USER_DEPREC
I´m lost.


If I set display_errors = Off it’s solved.

Is it very wrong to leave it like this in the production environment?

It is recommended to leave display_errors “Off” for production.

Good morning!

Ok then. I close the subject as solved!

Thank you so much!


Dear Cristina,
check your webserver logs for size - I also did the upgrade to to run OJS in PHP 7 and in my case these php warnings were piling up in the server logs and the logs can become huge. See these posts for the fix: Ojs 2.4.8-4 is compatible with php 7.3? - #12 by AlesKladnik, PHP 7 warnings filling up error log after upgrade to

If you downloaded the code from git using ojs-stable-2_4_8 branch this should be fixed, but the code in the OJS download page is missing this fix. This is the fixed file: pkp-lib/ at ojs-stable-2_4_8 · pkp/pkp-lib · GitHub

@asmecher Alec, is it possible to update the Download OJS 2.4.8-5 link with the lastest changes in the ojs-stable-2_4_8 branch on git?

Regards, Ales

Hi @AlesKladnik,

I’m not sure yet whether we’ll release another OJS 2.x package – it does take time and we’re much more focused on OJS 3.x; I’d encourage you to consider upgrading rather than maintaining OJS 2.x.

Hi Alec, yes I’m aware the priority is OJS 3, but our situation is similar as Cristina’s. Some of our editors are retired professors and they really don’t like anything to change, that’s why we’re staying on OJS 2 :frowning: And I’m not expecting to see any new OJS 2 releases :innocent:

We did a test installlation of one of the early OJS 3 versions, but they didn’t like it, one of the problems was selection of reviewers, it was easier in OJS 2. I’ll wait for the 3.2 release that as I read is going into user testing right now and then present a test install again.

Cheers, Ales

Hi @AlesKladnik,

OK, sounds good. And as always, if you have specific feedback on a particular feature of OJS 3.x, please send it along! It sounds like there’s something specific that’s holding your editors back.
