Hello,
I'm a web developer based in Austria and would be happy to help you fix your login page.
I have many years of experience in PHP and MySQL and have worked on projects for various organizations.
Normally when a session is created, the session contents are saved on the web server (not on the client's computer). A cookie (usually named PHPSESSID) containing only the session ID is saved on the client's computer. The session ID in the PHPSESSID cookie points to the session file on the server.
Do you want to keep this PHPSESSID cookie, which contains the session ID?
Looking forward to helping you.
