I had problems with my blog because I had made some changes to the theme style.css. That was before I knew about making child themes. Anyway, I changed themes and then changed back to my original theme, but I am still getting this one error message quite often. Sometimes I get it when making a blog post but the post still shows up fine. But today I was trying to upload a jpg file that I was going to use and I got the error message again. For a while I thought the image file had not been uploaded, but it turns out it was.
But I don’t know how to fix this problem with the error message I keep getting. It seems to be saying that the header is being called for in two different places, but I don’t know why that would be. The header file for my blog is precisely 1100 x 180 as recommended and I used the dashboard to upload/install it. Since re-installing the theme (bouquet), I haven’t done anything with the style.css or any of the functions or anything to put in the header. I have no style.css file at all in the child them folder - it’s just an empty folder at this time. Plus, the header displays just fine on my blog. I don’t get the error message when simply going to my blog site. It only happens sometimes when I am trying to post something new or upload an image file.
Here is the error message:
Warning: Cannot modify header information - headers already sent by (output started at /home/priscilla55/blog/wp-content/themes/bouquet/functions.php:1) in /home/priscilla55/blog/wp-includes/pluggable.php on line 1121
