I have a site built with wordpress (httml://ddforum.co.za)using a modified 2011 theme. It allows customized banners/headers/featured images, which I use extensively, each page has a unique featured image/header.
I started off having a log-out problem. Instead of taking me to a (redirected) log-in page (I'm using WP-Members), it errored as follows
"Warning: Cannot modify header information - headers already sent by (output started at /home/ddforumc/public_html/wp-login.php:58) in /home/ddforumc/public_html/wp-includes/pluggable.php on line 881".
It has now degenerated to the point that I cannot log-in but instead get the following message
"Warning: Cannot modify header information - headers already sent by (output started at /home/ddforumc/public_html/wp-content/themes/ChildOfTwentyEleven/functions.php:6) in /home/ddforumc/public_html/wp-includes/pluggable.php on line 680"
and the banners/headers don't display:
The message is repeated about 8 times, sometimes with different line numbers.
As I can't log-in to get to the dashboard and check the pages for it seems to me that I may have to re-install Wp, which I hope to avoid. So, I have two questions:
1) Has anyone had a similar experience and what should I do about it?
and
2) If I have to re-load Wp, can I do that without losing all my content or will I have to reload the content as well?
