PHP Warning: Missing argument 2 for expirationdate_add_column()

Hi,

We’re getting the following warning that keeps popping up and clogging our log files:

[Wed Jun 15 12:53:48 2016] [warn] [client 50.206.115.186] mod_fcgid: stderr: PHP Warning: Missing argument 2 for expirationdate_add_column() in /var/www/vhosts/sitename.com/httpdocs/wp-content/plugins/post-expirator/post-expirator.php on line 50, referer: https://www.sitename.com/wp-admin/index.php

What do we need to change to correct this? Is it something we’re doing, or something you need to address on your end?

I know it’s only a warning and most people would tell us to just shut them off. However, it’s making it difficult for us to address other errors in our log files since this repeats every 1 to 10 seconds.

Thanks!
