Title: Invalid feed, blank lines, function.php Last modified: August 19, 2016 --- # Invalid feed, blank lines, function.php * Resolved [M1chel](https://wordpress.org/support/users/m1chel/) * (@m1chel) * [16 years, 9 months ago](https://wordpress.org/support/topic/invalid-feed-blank-lines-functionphp/) * Hi, I have a problem that seems to affect many users: I get an error message when I try to validate my feed for feedburner. It says that I have some blank lines before the XML declaration. * > This feed does not validate. > * > line 1, column 1: Blank line before XML declaration [help] * It suggests to check the wp-atom, wp-rss2, wp-config files or theme specifics like th functions.php I know it’s not fault of my plugins coz it didn’t validate also without plugins. When I first checked I had 13 blank lines, then I erased some from the function file and now I have only 2. * I’m not sure where else to check, however can you take a look at my functions. php to see if I’m missing something? Or do you have a solution to fix the lines? * [code moderated] Viewing 6 replies - 1 through 6 (of 6 total) * [esmi](https://wordpress.org/support/users/esmi/) * (@esmi) * [16 years, 9 months ago](https://wordpress.org/support/topic/invalid-feed-blank-lines-functionphp/#post-1188439) * Please don’t post huge chunks of code here.

From what I can tell, these are coming from your theme’s header. php file as your web pages also demonstrate the same opening ‘blank’ lines. * Try editing header.php and removing everything before: * `` * Thread Starter [M1chel](https://wordpress.org/support/users/m1chel/) * (@m1chel) * [16 years, 9 months ago](https://wordpress.org/support/topic/invalid-feed-blank-lines-functionphp/#post-1188472) * uhm, I edited the header.php and also my custom home.php where the only thing before the doctype was * ``` ``` * now it’s gone but my problem is still there..

You may have to start going through every file looking for blank lines either before the opening `` tag. 🙁 * Thread Starter [M1chel](https://wordpress.org/support/users/m1chel/) * (@m1chel) * [16 years, 9 months ago](https://wordpress.org/support/topic/invalid-feed-blank-lines-functionphp/#post-1188622) * I looked for a while into the problem and I couldn’t find which file was affecting the feed. Finally I used this solution: [http://stiern.com/tutorials/no-more-invalid-rss](http://stiern.com/tutorials/no-more-invalid-rss) Yesterday I tried the same thing but with the .htaccess file and I damaged something important which got me to reinstall wordpress. I suggest you modify just the index file like described on that site. * Thanks Esmi for your time.
