I was uploaded my article and meta data using journal user id. If I click finish submission botton it will loading too much of time and also the process is not completed.
In cases such as these, where there is a continous loading, or spinning wheel it is best to check your PHP error log and report on errors found there. If you’re not sure about how to do that, please see this post: How do I find my PHP error log?
