Execute the following SQL query in your database:
SELECT major, minor, revision, build FROM versions WHERE product IN ('ojs2', 'omp') AND current=1;
dbscripts/xml/version.xml in your OJS installation. Find the release, e.g.:
This will tell you the source code version. Note that this may be different than the database version, e.g. if you’ve upgraded the code but not the database.
