Error with File upload

[Martijn]

In my working field we have large pdf reports and powerpoint presentations.
So on my forum I want users to be able to upload large files (max filesize = 64 mb).

I've uploaded a .htaccess file to the server with php_value upload_max_filesize 64M
Also I changed the Xenforo options to 65536 KB, maximum attachment size

First I could upload 2 MB-files, after the changes I now can upload 8 MB-files
When I upload a 16 MB file, I get the following error :

Security error occurred. Please press back, refresh the page, and try again.

The error doesn't give much info.
Is this an Xenforo error, or has it to do with my hosting company ?

Thanks in advance.

Check also a POST_MAX_SIZE value

Security error occurred. Please press back, refresh the page, and try again.

That error has to do with xenForo's security token which is included in all forms.

Just a guess... do you have suhosin installed in your PHP configuration? Suhosin sets limits on requests and can truncate requests exceeding those limits. I have seen this result in a security error before.

Changing The Post_Max_size did the job. Thanks Pepelac!
