Hello,

The version of OJS that you’re using is no longer maintained or supported by PKP.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

Once upgraded, our Google Scholar Indexing guide may provide further guidance on how to go about best using OJS with Google Scholar.
