Hi @Farhan_Abbas,
For the An unexpected error occurred. You may have been logged out. message, see other threads on this subject, e.g.: An unexpected error occurred. You may have been logged out. Please reload the page and try again
It’ll help organize the forum if you post one question per topic, rather than continuing an unrelated topic with a new question; search for the error message before you post to see if there is already a related thread, maybe with a solution. Include e.g. the URL you are going to that corresponds to the error in the log; if you don’t have it yourself, you can usually get it from the access log by correlating the timestamp. This helps to identify the cause of the problem.
