PHP Warning: Cannot modify header information

Hi,

Thanks for reporting, have to look into this. This might be a conflict with another plugin, because I don’t have this issue.

Guido

Downgraded to previous version and all ok now.

Was whole site down or only a warning?

Current version uses a cookie, somehow it causes the headers already sent issue in some cases.

Guido

Just the warnings on debug log.

Hi,

I have updated multiple sites but no issue with this. So I think it’s a conflict with another plugin.

Are you able/willing to do a test after you’ve updated plugin?
If you are, open the plugin editor, go to file vscf and look for:

add_action( 'init', 'vscf_cookie', 10 );

Change into:

add_action( 'send_headers', 'vscf_cookie' );

Does this solve your error?

Guido

I will and update here.

That change seems to fix the issue.

Thanks, I will update plugin today.
I may remove the newly added cookie feature again, because in some cases it may cause a conflict with other plugins and I don’t have control over that. This makes VS Contact Form less stable.

Guido

Hi again @dimalifragis

Did your warning/error only include a reference to my plugin or was there a reference to another plugin or theme as well?

Guido

Hi, no the error pointed only to your plugin.

Thanks, thought about it some more and will not add cookie again. Besides your issue there’s also GDPR (privacy) and adblockers that may cause problems.
