Error cache limiter – headers already sent

Hey JosepLluis,
This could be due to trailing spaces in a php file, if you had edit one, but assuming that you had not then the solutions in the past were:
1: A delay with the host deleting the Server Cache on the server after the theme update.
2: Host had changed/upgraded PHP versions and was re-directing to a new PHP handler in the .htaccess file
3: A bad plugin.
Fixes:
1: Try re-upload your theme and then rename your plugins folder, to plugins2 via FTP: https://vimeo.com/67209750 Or: http://kriesi.at/archives/the-complete-guide-to-updating-enfold.
2: Contact Host to clear server cache and check php.
3: Try adding this code at the end of theme / child theme functions.php via FTP:

add_theme_support('avia_no_session_support');

This is to get your site online to try to find the issue.

Best regards,
Mike

Hi,
Which steps did you try?
Did you rename your plugins folder, to plugins2 via FTP?
I see there is access to the backoffice login page, but you get the error after logging in?

Best regards,
