Hello. An OJS (3.3.0.14) has been set up for my new journal, I tried a new submission and it submitted successfully without any error message. But when on the submission page there is no submitted file shown, only display ‘Loading’ message as in the following:
In these cases where you are seeing a spinning loading wheel (or if you are getting errors like the 500 error) it is best to check the PHP error log to see the errors appearing there. The messages in these logs provide more of a clue as to what is occurring. If you post them here, then other users are able to assist in identifying what the issue is (and what you might do about it).
