When using RAYVN in your web browser, the browser saves some information while using RAYVN in its cache and cookies. Occasionally, clearing the cache and cookies fixes specific problems that some might experience during login, loading, or if there are some formatting issues while using RAYVN.
The problem is caused when RAYVN and it's services have made some changes, and your browser is using an old "version," stored in its cache/history.
