Title says it all, I am enable to login to /wp-admin... The problem is that I changed NOTHING in the codex or something, I just logged in 3-4 days ago and everything was fine, but yesterday, nothing, my panel didn't work...
My website is : francoispoirier.ca
An error message appears when typing /wp-admin, here it is :
Warning: Cannot modify header information - headers already sent by (output started at /home/content/42/9256642/html/wp-content/themes/Openhouse/functions.php:1) in /home/content/42/9256642/html/wp-includes/pluggable.php on line 876
I can still go on my website normally, but can't access to the control panel...
Can anyone help me ?
My knowledge in computer is limited...
Thank you for any help you give me,
