Sir if I fill rg ID password rcu capta Then logged in but it is showing you are already logged in but how can I get payment and city choice

Dear Nayana, please clear the cache, browsing history, cookies, etc. Try restarting your system and relogin. Last time around when there were same technical glitches, students tried this and it worked for them. It might take a while but eventually you will be able to complete the process. You can only select the Examination city now. You cannot make any payment.
