That's the error message my users usually get when they try to upload a file type that hasn't been allready approved. Could that be the issue?

SGL.

Thanks for helping Triff, but unfortunately it isn't that issue. Only admins and supermods have upload rights on my forums.
In my case it's a file i'm trying to upload myself and it's extension is .rar, upload that numerous times. So it can't be a permissions or unapproved file types.

Is there a way so we can put in a megaupload link that lets users then click download and it opens the megaupload/rapidshare site where they can then enter their verification code as normal?

Basically, can we put URLs in the Link to File form with it not ending in a file extension?

Adding custom fields isn't possible at the moment.

You probably get it because it's a large file (so it's timing out and vB doesn't receive the token). Do you get it when you only link files?

You need to change PHP's upload limits for this (.htaccess or php.ini).

Yes, you can. There's no check on the link field.

Thank you! Installed :D

I don't think this is the problem, because it's a file of 9 mb and normally I upload files of 16 mb
The php.ini is setup to 25 mb so that should not be the problem either.

I will check if the error also occur's when linking to files.

I've just seen the files of 16mb are linked too. Linking is ok, no problems there. So I think you indeed were correct with the assumption that it had to do with big file uploads.

However, it still says in php.ini:
file_uploads = On
upload_max_filesize = 25M
default_socket_timeout = 60

Is there another place where I can change something so bigger file uploads won't time-out? I've got all access on that server including root access.

What's your AdminCP home saying (PHP ... PHP Memory Limit)?

Just to be sure that those settings are actually working :)

Thanks Jelle, I think I got some idea's about where to look:
max_execution_time = 30 ; Maximum execution time of each script, in seconds
max_input_time = 60 ; Maximum amount of time each script may spend parsing request data
memory_limit = 16M ; Maximum amount of memory a script may consume

Seems the memory limit is oke for a 9 mb big file, but the max. execution time is limited to 30 secs, which might cause the upload to stop, correct?

In that case for security reasons (shared server with a lot of accounts) I can better leave this as it is now and upload the files by ftp and link to it.
