I have checked them, but they seem ok..... what file you think I should check particularly....?
Or have I to check everything??!!!!!!!
Is there a section where I can check first????
I already checked, attachment.php, config.php, settings.php, init.php.....

Could you PM me your ftp login. It would be easier and faster for me to get in and look at the files that way since it looks like you're not even sure what to look for.

EDIT:
The problem was in the inc/plugins/attachmentlog.php file, there was extra white spaces at the end of the file.
Its not necessarily a problem with that plugin because I noticed alot of your files have extra spacing that should not be there. Do you use the host's editor to open/edit the files? If you do I recommend not to and use something like notepad++ to avoid similar problems in future.

Problem solved! Thank you G33K!!!
Awesome!
