CMS CMS crashes when some mods are turned on....help please.

[محروم.كوم]

Our mods were working fine with 4.0.2
We upgraded to 4.0.3 and now we are getting error messages and our CMS crashes when certain mods are on.
For Example: When we turn on our ad banner rotator mod our CMS goes down and we get this message:
Fatal error: Call to undefined function rbs_url_sanity() in /home/content/92/5987292/html/mx/forum/includes/functions.php(6811) : eval()'d code on line 62


The coder says the mod is 4.0.3 compatible __DEFINE_LIKE_SHARE__
