Describe the issue or problem
Our journal running OJS 3.1.2.4 hosted here https://stratfordjournals.org/journals/ was initially indexed by google scholar properly but after a short downtime and hosting migration, all articles stopped showing up on Google scholar. All sitemaps are updated in google and all meta-tags are in place for all articles.
Steps I took leading up to the issue
I installed OJS 3.0.2.0 then upgraded to 3.1.0.1 and finally updated to 3.1.2.4 in May 2022.
Things were fine, articles indexed in google scholar…
At some point, the journal hosting went down, we migrated to another hosting during which some files(galleys) were lost. We re-uploaded them after migration and since then, all other articles do not show up in Google scholar even though they are visible in google search. Tried searching the site site:stratfordjournals.org in google scholar and no results were found.
What application are you using?
OJS 3.1.2.4
Additional information
I have Google Scholar Indexing Plugin enabled for all journals
Was in touch with google and they helped remove some 404s on the journals but this did not fix.
This journal has over 3000 papers/articles.
Kindly help get back these articles into google scholar
