[Plugin: Password Protect WordPress Blog] Warning: Cannot modify header information

Hi Mike. That error is caused by some whitespace. Could you pastebin.com the contents of doctype.php for me so I can tell you what is wrong.

Yea, awesome. https://pastebin.com/fc1Kvqdb

Interesting. What theme are you using?

Have you got “enable cookies” on in advanced settings?

This is the theme I am using: https://themeforest.net/item/los-angeles-a-premium-wordpress-theme/84768

I don’t know if I have enabled cookies. Do you mean in Firefox?

I meant in the plugin.
Try replacing the contents of index.php with https://pastebin.com/JutEgNGW

I’ve got to go now so if that doesn’t sort it then i’ll take another look tomorrow.

Regards,
Daniel Chatfield

Will do, thx
