[SM-PLUGINS] PHP Warning in Unsafe Image Rules Version 0.7

[William H. <w1...@pr...>]

I'm seeing the following in the ..../httpd/error_log:

[client 10.1.15.115] PHP Warning:  preg_match_all() expects parameter 2 =
to
be st
ring, object given in ..../plugins/unsafe_image_rules/setup.php on line =
247,
referer:
..../src/printer_friendly_main.php?passed_ent_id=3D2&mailbox=3DINBOX&pass=

27

Server config is SquirrelMail 1.4.4, Cyrus 2.2.8, PHP 4.3.10, =
Apache/2.0.51
on FC2.

Please advise how to proceed to remove the PHP Warning.
