[ksugar]

Hi all! I am a new user in this forum.
I use for job SugarCRM and i get a strange behavior about a function named cache_file_name_only() in class Relationship. When i use this function this page does not show (page not available). But if i comment this function i get the page display in browser screen. This effect is through the link "index.php?module=Users&action=DetailView&record=. .." .... anyone can help me ?

Operating system type and version Linux SUSE 10
Sugar Suite version no info
Webserver type and version Apache 2.0.58
PHP Version PHP 4
MySQL Version 4.0.5

Are you making changes to the code or just using the stock code base?

If you are making changes can you describe/Show those changes?

No no, i have make no change to code in sugarcrm.
Only i have just see this behavior in that "module" not only for this (module "User" is my personal example bug (if this is a bug)).
The base class is Currency (for money). If i comment this class the call to other class not work (and the class to this function) but i can see the page. if i de-comment the call of this class (and all other class included) the code cannot find a page or other module (or so on).
