[Typo3] Real Url Stalling Errors

[Raymond Hayes]

Hello
  I am having issues with Real Url. What happens is the site will work for
 about a day or so, then the site stalls when accessing the home page. If
 I remove real url out of the backend, and reinstall, it works again for
 about a day or so. Then the page stalls and will not load.
  One item of note is when I look in the backend under WEB:INFO, I have
  errors, listed like so..

Warning: array_unshift(): The first argument should be an array in
/srv/www/htdocs/evangelize/typo3conf/ext/realurl/modfunc1/class.tx_realurl_modfunc1.php
on line 487

Warning: Invalid argument supplied for foreach() in
/srv/www/htdocs/evangelize/typo3conf/ext/realurl/modfunc1/class.tx_realurl_modfunc1.php
on line 492

I have Typo V 3.7.1, Latest version of Real Url, Suse 9.3 (Apache 2.0.53)
(PHP 4.3.10)
Any help would be appreciated
Thank you
