Cannot modify header information warning

  • I read that I simply have to remove white space at the offending line when I get this message: Warning: Cannot modify header information – headers already sent by (output started at /home/content/67/5962867/html/wp-content/themes/lupercalia/functions.php:892) in /home/content/67/5962867/html/wp-includes/pluggable.php on line 1121

    I couldn’t figure it out and it wouldn’t let me upload pictures, access my media libary, or even log in, so I changed back to my old theme and then back to this one. I still can’t load media and now have about twenty of those error messages, although I can at least log in and out of my admin page.

    Hey there,

    you are the second person talking about this error. It was not happening before, so I think it is related with the newer WordPress version.

    Can you confirm if you updated your WordPress recently?

    This girl seems to have solved the problem.

    It is not related with the theme, I think it is related to the newer WordPress as I mentioned before.

    Thanks, that solution worked, but I still get errors cropping pictures for the header, and the slider native to the theme won’t show up (my site is blog.thegreciangarden.com). I tried making a new home and blog page, but that didn’t seem to make a difference as I still don’t see a slider. Changing the settings in theme options and going with a static page didn’t seem to matter either. I could just have a bug as recent post sliders on my old theme would never work.

    Bloogooroo,

    can you be more specific about the error? Could please post the message you are receiving when you try to upload a new header?

    Thank you!

    Image could not be processed. Please go back and try again.

    It will work if I skip cropping. I don’t want a header though, just a slider. The problem might be that I got rid of the home page, but now I put one back on and it still doesn’t work.

    It is wark to know if it is related with the theme, it was working fine before. I am still looking for a anwser.
