Listing Detail page just blank white

... I have actually found some errors now.

#5416 - E_USER_ERROR: setPrefixedCookie: Can't set cookie(loginsession, ==Qf0QDN5cDOyYTNxojIzNXZjNWQ0NXYsJCLiMGM1IjYkJmZmRmMmZGZhNjYhlTOwQGOyIjYwYzYiVjN5gzYmFmZwMDJxEGazRiI6ICazFGSkJ3b3N3chBnIsISbvNmL05WYoNmcl1mYhxGQulWbkFmI6ISZtFmbyV2c1Jye), headers already sent!

And here is another error:

#5415 - E_WARNING: Cannot modify header information - headers already sent by (output started at /home/sites/8b/7/786382f535/public_html/create-advert.php:3)

I'd be really grateful if someone could explain how I can fix these.

Hi Greg,

Those errors are generally caused by some whitespace existing above the script tags. You can try to find and remove this whitespace, or you can try Dave's solution here: https://www.interactivetools.com/forum/forum-posts.php?postNum=2243220#post2243220

Let me know if you're able to resolve the issue, or have any other questions!

Thanks,

Hi Daniel,

That was the problem! Thank you very much for sharing this with me.

Regards,

Greg
