After upgrading from OJS2.x to 3.0.2.0, OJS stuck in Step-1 of new submission.
This although creates a new Submission ID in Submission table of DB, but at User-Interface, only the spinner keeps spinning and does not move ahead to next step. Even clicking on next step if not working.
In the browser-inspect-module this shows the error like “Failed to load resource: the server responded with a status of 500 (Internal Server Error)” for “saveStep/1:1” (https://researth.iars.info/index.php/curie/submission/saveStep/1). Although I can access the script in the browser, means this is accessible at least.
Can someone please help?
