I cannot delete an existing cookie which is set with PHP. I'm sure that it is set with PHP because, if i clear my cookies + disable JS it is still appending.
I can see this cookie appended for example: www.domain.com and the path to the cookie seems to be "/". I have tryed a LOT method described here but nothing works... the cookie is just there. Another interesting thing is that i can even get + echo the value of the cookie. It is not a session cookie.
My need is only to find a way to delete this cookie :/
Usually when you delete a cookie, you set the cookie again, but with a expires value somewhere in the past. Have you done this?
Have you tried to set empty cookie value and expired time 0?
Since you typing also in cyrillic, check if the cookie name if written with latin symbols or is mixed with cyrillic/latin by mistake (happened to me - you know that some chars are looking absolutely the same). Or you may have trailing space/new line at the end in some of your include files that force sending the output. Put ob_start() in the very beginning of your bootstrap php file.
