   Hi,

   I have update to the 0.9.2.2 from plugins page (update automatically) but after that, i got two same error:

   Warning: Cannot modify header information - headers already sent by (output started at /home/guglingc/public_html/wp-content/themes/Gugling/functions.php:130) in /home/guglingc/public_html/wp-includes/pluggable.php on line 897

   Warning: Cannot modify header information - headers already sent by (output started at /home/guglingc/public_html/wp-content/themes/Gugling/functions.php:130) in /home/guglingc/public_html/wp-includes/pluggable.php on line 897

   Then i click on: returns to the plugins page and go to the W3 Total Cache page settings. I found error again:

   Then i go to /public_html/.htaccess to add the following rules (before this, i try to click the auto-install but it doesn't work)

   After add the following rules, i upload .htaccess using FTP and replace the old one. Then, i click on clear all cache but it doesn't work.

   Then i use other browser to login and got the new error:

   Warning: Cannot modify header information - headers already sent by (output started at /home/guglingc/public_html/wp-content/themes/Gugling/functions.php:130) in /home/guglingc/public_html/wp-includes/pluggable.php on line 897

   Now, i can't login to my backend. Please help me :(

   Thanks.

   Via FTP, I would I would delete the w3-total-cache plugin and see if you can log back into the admin. Hopefully that should fix it, then either try to reinstall and see what happens.

   If it happens again, then it might be in conflict with another plugin.
   You could try deactivating them one by one and see which one is conflicting.
