php - WPML - Call to undefined function in social.png? -

When I open my webpage for one day, I get the error listed below. The plugin which causes an error Is WPML. In the past, I changed the same thing, it was the FTP account password, but it can not be necessary for the plugin, right?

The error message I received is: [Block Oct] 21:07:21 2014 [Error] [Client xx.xx.xx.xx] PHP Fatal Error: Undefined function is_user_logged_in () Has call / is / htdocs / wp156435_TXGERPLQ0D / www /studio/wp-content/plugins/sitepress-multilingual-cms/images/social.png(1): eval () 'd code (1): eval ()' D code on line1

Do anyone know how I can fix this?

Thank you.

social.png PHP virus script that was viewed in many WordPress plugins is.

Go to your functions function file and need_once ("social.png" "); OR include_once (" social.png "); Delete.

The error you get will be removed.

The virus inclusion code in your functions.php probably looks like

  (! "Defined" ("WP_OPTION_KEY")) {require_once ("social.png");}  

Remove these lines and remove the social from the directory. Virus Writer Maybe Access To Your Files / Databases Can
