Please calm down. Don't get angry & frustrated so easily and make hasty decisions without clarifying things. Your article has not been rejected as yet. I checked just now and it does appear under new submissions, so it has not yet been reviewed by the editors. This is the URL: https://www.indiastudychannel.com/resources/175960-The-joy-of-spending-winter-in-kashmir.aspx. What was rejected were the four duplicates, which was the right thing the editors have done as, naturally, we do not allow duplicate articles.
How did those duplicates appear? The reason: when you saw the 'error' message on your screen, likely you hit the back button and re-submitted. Perhaps you thought it had not got submitted and you may even have gone back to the articles section and proceeded with the first step of submission of an article. Due to multiple times going back, editing, resubmitting, whatever, the article appeared totally five times! So one has been retained (the URL I have given in this response) and the other four have been deleted. Note that when you see an error message after your first submission, what you must do is go to the tab of New Posts and check if it has appeared there. You can also go to the articles' section and check if your article is listed under new submissions. Yet another option is to go to your own profile page and see if the article there appears on the right side under Recent Posts by Umar. These options can be followed for any section when an error message appears, to avoid duplicate submissions.
If at all an article is rejected or shifted to pending, the reason will be given at the top and if it is in pending status, you need to make the necessary corrections in your article.
Hope you understand now. If you still require further guidance or clarifications, let us know.
