form_tag cause error on production

dear, I just deployed my first rails application and it failed

when I checked the log file on the server, i got the following

ActionView::TemplateError (wrong argument type FalseClass (expected Proc)) on line #13 of daleel/_top.html.erb: 10: <center> 11: 12: <div id="navigate"> 13: <% form_tag :action => :navigate do %> 14: <table> 15: <tr>

any idea why is it behaving like that on my localhost there is no error in development and production env

thanks

Have a look through the group archives, but I have a vague
recollection that ruby 1.8.6 p230 does that.

Well I do not find any useful info on google search I am just wondering why the server fails on this part of the code. However, sometimes it works.

Strange???
