Recently, I rewrote config.php to increase cache size to 64 Mb to compensate for a "cannot write" error. A day or two later, I tried to perform an automatic update to WP 3.3, and received this error message:
Warning: Cannot modify header information - headers already sent by (output started at /home/riverwri/public_html/wordcurrents/wp-config.php:49) in /home/riverwri/public_html/wordcurrents/wp-includes/pluggable.php on line 934
I consulted the forum for this error, and discovered I should try disabling plugins; however, any admin tab I click on returns that error. Pressing the "back" key allows me to return to the Admin Dashboard, but I can load no other page in the admin.
My blog is at http://riverwriter.ca/wordcurrents
What do I do next?
