Warning: Cannot modify header information,…

Second “headers already sent” this morning… ??

https://codex.www.ads-software.com/FAQ_Troubleshooting#How_do_I_solve_the_Headers_already_sent_warning_problem.3F

The only thing I’ve done is added tracking code from google analytics to my footer.php file. Would this cause this error?

My guess would be the footer.php file. If you have a backup of that file or know where you got the theme from (it’s with your theme) then try putting back that un-edited version of that file back.

if the problem goes away that’s what did it.

Side note: Google Analytics can be added easily via a plugin. In the past I’ve used this plugin but there are many others.

THanks Jan,
UNfortunately this morning I can’t even log into my dashboard to make the changes you suggested. I was able to last night despite this error message.
Now when I try to login I get this-

FTP into your site (or use whatever file management application your host provides) & delete the wp-content/plugins/polldaddy folder.

Check that there are no blank spaces (including new line breaks) at the end of your functions.php.
