After login with wrong credentials no page shows

-- url of the page with the problem -- : mywebsite.com/mypage
-- HikaShop version -- : 2.2.1
-- Joomla version -- : 3.1.5

When tryin to log in with a non-existing user-name (for example by using the e-mail instead of the user name) or with a wrong PW, Hikashop does not open an error message on that site but displays a standard browser error screen with the notice:

0 - Cannot open file for writing log

Hi,

I think that this is a webserver issue, so reading this post will probably help you :

I found out that the error had been caused by the values assigned to the $log_path and $tmp_path variables - I had used a path relative to the web root and not absolute values.
Correct values were

$log_path = '/var/www/vhosts/mysite.com/subdomains/clients/httpdocs/Sacred/logs';
$tmp_path = '/var/www/vhosts/mysite.com/subdomains/clients/httpdocs/Sacred/tmp';

yep. Wrong hoster-specific pathes. Thanks for the help!
