warning: implode(): Bad arguments... in trip_search.module, line 302.

Hi,

I'm new here. But I have done my fair amount of searching and I can't find the answer specific to my problem.

Installed trip_search.module. Now I'm getting these errors:

warning: implode(): Bad arguments. in /export/home1/u03/usr/local/apache/htdocs/kb/modules/trip_search/trip_search.module on line 302.

...one per searched item found, at the top of the page. The line in question is...

return implode(',', $keys);

This is on Drupal 4.6.5.

Is there a fix/patch for this problem? I also can't find anything in the bugs section.

As I get more familiar with Drupal and this site I will be able to locate solutions faster and perhaps contribute, but I'm stuck right now! Please don't get angry with me for being a rookie or for not trying (because I am trying and searching).

Thank you!
