Embebed PDFs are not displayed

Dear Sirs,

We are getting an error while trying to display embed article pdfs. We get the following: https://erevistas.uca.edu.ar/index.php/RPSI/article/view/4238/4207

The download link works, but we cant’ read online the article pdf.

There is another plugin: “Google embedded viewer Plugin”, that solve this, but I would like to know if there is a way to solve the problem with the original visualization of article pdf.

We have OJS


Hello @EzequielEsposito,

Please note that version of OJS that you’re using is no longer maintained or supported by PKP. I recommend that you upgrade to the newest version of OJS. However, other community members may wish to offer assistance with your question.

You may find the following resources helpful in preparing for and performing the upgrade:

These resources will introduce you to OJS 3 and how it is different from OJS 2:

You may need to seek professional support to upgrade your installation. This can usually be acquired from the service provider that hosts or maintains your software, such as the technical support team at your institution or a third-party hosting provider.
