MyBB Community Forums

I'm using Mybb v.1.2.14 (PHP 5)
I have patched my forum for each Security Update

Now I'm following http://community.mybboard.net/thread-39705.html
but after I applied the patch, if I try to download an attachment, I obtain

500 internal server error

I think the patch for attachment.php is wrong...

Thanks for help

What does it say in your Server Error Logs?

"500 internal server error" is the title of error page... The page suggests send the error to admin.
Where can we access to Server Error Logs? Perhaps in MyBB Admin Panel?

I resolved using "chmod a+x" on the new file.php , thanks!
I'm a noob! Sorry!
