I have installed koha.When I access OPAC web interface with ie7，there is webpage error in the left down corner.

And there are some error msg in apache error log.

Error msg:

opac-search.pl:PARAM:LOOP:next_loop:hash pointer was expected but not found at /usr/local/lib/perl/5.8.8/HTML/Template/Pro.pm line 191.

opac-main.pl: PARAM:LOOP:next_loop:hash pointer was expected but not found at /usr/local/lib/perl/5.8.8/HTML/Template/Pro.pm line 191.

Platform: Debian4

koha version : koha 3.0000094

HTML::Template::Pro version : 0.71

How to solve it?

Thanks

Best regards,

Wilson
