hi, i've a strange problem with facebook pixel on a joomla website;
the pixel helper shows that is installed, but when i try to create an event action in the business manager to track the "contact button" or anything else, the tools don't shows up.

tried to speak with the help desk and they told me there's a line of code that interfere with the pixel, but they don't want to tell me what is.
for sure it's not a joomla issue 'cause on vanilla installation and it's the same issue.
also i've tried on another websites on another hosting and it's working, so i assume is something related to php/apache
i don't know if is a php extension or apache config, but i need to find the solution.
i can't find where the issue is located, in the logs i don't see nothing, so i don't know where to look at

any help pls

    Hello, it is recommended that you press F12 on your browser to enter developer mode, click on the network interface, and then operate the website to check the reason.
    Also check for errors

        aaPanel_Kern
        The problem is on cross origin opener policy

        Facebook told me that I have to disable same origin

        Where I find this ?
        Maybe is xxs cross origin protection ?

            aaPanel_Kern where to configure?
            in the websites configuration or in apache configuration?
            what line of code i should add or remove?

              nevermind.. i found a solution, i had to disable the http headers plugin in joomla 😃
