I am pulling in various logins from my CSV file using the CSV Data Set Config. I am manually able to log in as each user. When I run the script in jMeter, I am able to login as every user except the first (happens with/without the "ignore first line" checked). I get a 403 Forbidden error and the response data says "invalid login."
I don't get why this is happening. Can I get some suggestions, please?
