Ever since I updated to 3.9.1 I have been getting the following error message whenever I wish to preview a post (and also whenever I publish a post. It gets published but I get the error anyway)
Notice: Undefined offset: 0 in /customers/3/c/7/konstantia.com/httpd.www/wp-includes/capabilities.php on line 1102 Warning: Cannot modify header information – headers already sent by (output started at /customers/3/c/7/konstantia.com/httpd.www/wp-includes/capabilities.php:1102) in /customers/3/c/7/konstantia.com/httpd.www/wp-includes/pluggable.php on line 1121
I have deactivated all the plugins I have installed lately but nothing changes.
I have also downloaded the zip of the 3.9.1 version and uploaded the two files mentioned above again manually.
I can see that I am not the only one having this problem. Does anybody know why this is happening and if I can do anything about it?
