error CSRF ATTACK

Hi,

I have OCS installed in version 2.1.2 and all menus work normally, except when I click on "search with various criteria" the error occurs:

CSRF ATTACK !!!

In the apache error log (/ var / log / httpd / error_log) nothing appears and I have already raised the log level to "debug" for maximum detail, but it does not show anything.

In the access log (/ var / log / httpd / access_log) shows:

10.17.228.56 - - [10 / Apr / 2019: 16: 16: 55 -0300] "GET /ocsreports/index.php?function=visu_search HTTP / 1.1" 200 16220 "http://10.17.228.255/ocsreports/index .php? function = visu_search "" Mozilla / 5.0 (Windows NT 6.1; WOW64; rv: 51.0) Gecko / 20100101 Firefox / 51.0 "

10.17.228.56 - - [10 / Apr / 2019: 16: 16: 57 -0300] "POST /ocsreports/index.php?function=visu_search HTTP / 1.1" 200 11534 "http://10.17.228.255/ocsreports/index .php? function = visu_search "" Mozilla / 5.0 (Windows NT 6.1; WOW64; rv: 51.0) Gecko / 20100101 Firefox / 51.0 "

I have already increased the parameters in "/etc/httpd/conf.d/ocsinventory-reports.conf"

    php_value post_max_size 1001m

    php_value upload_max_filesize 1000m

And in "/etc/php.ini"

    post_max_size = 1001M

    upload_max_filesize = 1000M

Is there another way to view the error log?

Tks!!
