OJS Crossref DOI problems to install plugins

Hi everyone, someone help me solve a problem that I have regarding OJS Crossfer configuration, import / export?
The problem is that the system asks me for plugins and I do not know how to ahcer this. Please, help me !!

Hi @agallalin,

What version of OJS are you using? (Please include this information with your posts.)

OJS 2.4.5.0 version

Hi @agallalin,

You’re seeing ##messages.like.this## because the Spanish translation of the CrossRef plugin is incomplete in OJS 2.4.5. Upgrading to a newer release (e.g. the latest OJS 2.4.x would be easiest) will resolve it.

How can I upgrade to the latest version of OJS ???

Hi @agallalin,

See docs/UPGRADE in any OJS download package.
