Hi,
I have over 9 years of experience in Java/JEE based enterprise web application.
I have worked extensively on HTML, Javascript, JQuery, Angular JS etc for UI development.
I have worked with various Product as well as service based MNCs like Polaris, IBM, Atos etc and also worked across multiple domains like Banking, Insurance, Automobile, Supply chain management, CRM etc.
I strongly follow processes and give importance to developing secured applications and data security.
This problem (as explained in description) could be because of browser upgrade if being accessed from single machine, else it can be a script issue.
