I have that awesome header error that a lot of people seem to get.
I have checked options.php, pluggable.php, functions.php, wp-config for any extra spaces using dreamweaver and believe me, there are none.
This issue was not there a few weeks ago, and just arose after no significant changes to the site.
Have tried deavtivated all plugins- no change. (it actually shows up even when I try to do this)
Odd part about it - when making a new post and hitting publish the error shows up, but when I refresh the post was made. It shows up on my site, but when I try to actually view the post online it takes me to a 404 page. The excerpt does appear though.
Here is my specific error:
Warning: Cannot modify header information - headers already sent by (output started at /services7/webpages/e/-/e-ternity.ca/public/wp-content/themes/qresponsive/options.php:1) in /services7/webpages/e/-/e-ternity.ca/public/wp-includes/pluggable.php on line 881
Any help would be so appreciated you have no idea.. I've been reading similar forums for a few hours now with no luck..
