i followed still happening.

 

if need url can post one.

 

thanks in advance

a php "notice" informs of non-fatal error. particular notice warns script trying add $cat_link nonexistent variable, $rtn_cats_link.

 

you can rid of warning adding following line before line 80:

 

$rtn_cats_link = '';

 

alternatively, can change settings error_reporting in php.ini this:

 

e_all & ~e_notice

 

that suppress generation of php warning "notices".

 

however, fact you're getting bunch of notices free script indicates has been sloppily written. there might other, more serious problems it. use care.
