[seo]

Hallo there, nice to meet you,

 

 

got a warning message from the server. Shop did not open:

 

Warning: Unknown: failed to open stream: No such file or directory in Unknown on line 0

 

Warning: Unknown: Failed opening '/tmp/anti_spam/anti_spam.php' for inclusion (include_path='.:/usr/local/lib/php') in Unknown on line 0

 

Do you have any idea what is going on and what to do against it?

Regards SEO
