Hi @haq,

I suspect the Acron plugin is getting activated or something similar. I would strongly suggest upgrading to the most recent OJS 2.4.x release before debugging further – this may well have already been fixed, and the upgrade from 2.4.2 to 2.4.8-1 would be non-invasive.

hi

there is no Acron plugin in ojs2.4.2 and i had disabled all other generic plugins and checked but still it is showing the same error.
any other thing that is causing this error?

Hi @haq,

There’s a very good chance that a minor bug was fixed between OJS 2.4.2 and 2.4.8-1, and it’s generally a good idea to keep up to date. I would suggest upgrading to 2.4.8-1 before spending more time debugging this.

Hi @asmecher,

Thanks for the suggestion. I’ll try to upgrade my ojs installation to latest version
