Hi folks,

I was wondering if someone could help me with an issue we are having with our LimeSurvey. We are currently using an older version of LimeSurvey (Version 1.87+ Build 8518)

This morning we received complaints that all surveys were showing this on the top of the page:

Notice: Undefined variable: xx983v in /srv/www/htdocs/survey/index.php(1) : regexp code(1) : eval()'d code on line 1
Notice: Undefined variable: xxq3aq in /srv/www/htdocs/survey/index.php(1) : regexp code(1) : eval()'d code on line 2
Notice: Undefined variable: x918zp in /srv/www/htdocs/survey/index.php(1) : regexp code(1) : eval()'d code on line 3
Notice: Undefined variable: x36opv in /srv/www/htdocs/survey/index.php(1) : regexp code(1) : eval()'d code on line 4

As far as I know nothing was changed.

Any idea's on what could have caused this?

Thanks,
Aaron

We don't use eval()' on line 1 or 2 or 3 ..

Then you php file are updated by someone else. You can replace the file by a clean file www.limesurvey.org/en/archived-releases/...24-archived-releases

eval is surely a hack. You have surely a virus attacking to your ftp tools to pit this on your server.

1st : change your FTP password
2nd : never 'remind my passord' in your ftp tool
2nd : replace the php files wit a clean LS core file
