Hi @brunoskyny,

Please include more information – what software you’re using, and what version.

Have you made any changes to plugins? I suspect there’s something there that’s causing trouble.

I am using the OJS version 2.4.6. I made no change in the plugin, just installed the plugin public identifier, I enabled, went settings, filled items and appeared this error.

Hi @brunoskyny,

Do you mean the public identifier plugin? How did you install it?

Hi @brunoskyny,

Just to confirm, all you did was enable the “URN” plugin?

I’ve tried that locally and didn’t encounter any problem. How did you upgrade? Can you double-check that the contents of the plugins/ directory haven’t somehow been changed?

I enabled the PLUGIN that was the DOI

the plugins directory was not stirred, but I installed a new theme, I do not know if it influenced.

Hi @brunoskyny,

What theme plugin did you install, and how did you install it? I’d suggest temporarily removing it to see if it’s causing the problem.
