File permission problem

[martinpaul]

Hello

 

I built a component for a non-profit organisation which want to use the 404page to promote several charities.

In order to do that I want to place a file 'error.php' in the map 'templates/system'.

 

I use the RENAME function for that.

 

So far so good. On many sites it works fine, but on other  sites I get an error on the rename function.

 

The user-id and the group-id of the script I use are the same as the uid's of 'templates/system'. So there shouldn't be a problem.

 

If I add public write to the filepermissions of 'templates/system'/ with Filezilla the error disappears. But I can't do that with the php chmod function, again because of too less priviliges.

 

HELP, I can't find an explanation for that and that's driving me crazy.

 

Thx in advance
