I have been using an inventory application built on PHP/MySQL. Since this morning I could submit the data and they were perfectly reflected on the MySQL Table. However, for a few hours I cannot save the submitted data to the table and it doesn't show any error message. Please note no change have been made since it was successfully running. The developer of this application is not available right now. PLEASR HELP I AM A NOVICE IN PHP/MYSQL.
