The error messages tell you everything that you need to know:

The file ‘wp-content/plugins/popup/popup.php’ is trying to do something bad at line 34.
You’ve also got another plugin for ‘WsiFront’ that’s trying to eval() something, and under 99% of circumstances, that’s very bad. It could be OK with this one, but me being to concerend would not use this plugin either.
If you have youe heart set on using both of these, look at your wp-config.php file and look for this line:
define('WP_DEBUG', true);
and change it to:
define('WP_DEBUG', false);
That will block the warning messages that you’re seeing.
