It is certainly not an administration access error. It occurs in accesses that are not from my IP.
Also now more errors are being produced:
PHP Warning: Attempt to read property "parent" on null in /home/videosvirales/public_html/components/com_k2/:on line 502
PHP Warning: Attempt to read property "alias" on null in /home/videosvirales/public_html/components/com_k2/: on line 502
It should be added to the end of com_k2/ router[.]php which is removed when you save the comment
