Hello,

System don’t generate 403 errors. I suspect file permissions. Can you please check files and folder permission and owner. Owner should be your web server www-data while file should have 644 and folders should have 755 permissions.

If still same, let me know the install URL with owner account details. You can post private reply by enabling the PRIVATE for Staff only at top right of reply section.

Thank you

Hi, I tried it with Firefox and it worked but It gives me 403 error in Chrome browser.

Please let me know how do I fix this?

Thank you

I tried with Firefox again to add another user and it has the same issue on Firefox as well as Chrome.

Turns out it was the password issue which is causing this trouble. I used the password generator from Firefox browser to generate a password and it worked on FF and Chrome as well.

Okay, I am glad to know that you have figured it out. Thank you for updating
