I ran into a very odd issue tonight with a brand new install of 1.5.1. I installed EP4.0.19 and everything was working great. However, after installing a bunch of other mods (37), it appears that EP4 was broken somewhere along the way. All I am getting now is a blank white page when I try to go the EP4 via the admin panel. I am getting the following message in my error logs:

PHP Fatal error: Function name must be a string in /home/corg/public_html/admin/includes/functions/extra_functions/easypopulate_4_functions.php on line 512.

Here is what line 512 looks like in that file:

$string = ($ep_uses_mysqli ? "MySQLi" : "MySQL") . " error ".($ep_uses_mysqli ? mysqli_errno($db->link) : mysql_errno() ) . ": ".($ep_uses_mysqli ? $mysqli_error($db->link) : mysql_error())."\nWhen executing:\n$query\n";

If I remove the dollar sign in front of "mysqli_error($db->link)" above, the white page goes away and EP4 comes up in the admin panel, but there is an error message that says, "Warning An SQL error has occured. Please check your input data for tabs within fields and delete these. If this error continues, please forward your error log to the Easy Populate maintainer".

I have seen other posts in here with the same message, but different error logs. I'm thinking this must be a different issue. Any ideas about what might be happening on this one? Thank you.
