Dear Sir,

My website install in wordpress latest & under site the settings
SuEXEC is checked
Php- Fast-CGI

While accessing my website, I get an error
HTTP Error 500 (Internal Server Error): An unexpected condition was encountered while the server was attempting to fulfil the request.

Under log (/var/log/ispconfig/httpd/mydomain.com#)

the error is

mod_fcgid: stderr: PHP Fatal error: Call to undefined function curl_init() in /var/www/clients/client1/web4/web/~

Other settings (/etc/apache2/mods-available#) vi fcgid.conf

<IfModule mod_fcgid.c>
AddHandler fcgid-script .fcgi
FcgidConnectTimeout 20
PHP_Fix_Pathinfo_Enable 1

</IfModule>

Please advice where is the problem

Thanks & regards

Seems as if the php curl module is not installed on your server. You can install it with the command:

apt-get install php5-curl

then restart apache.
