    I'm trying to make a thread with a 25MB attachment. The file uploads, but when it finishes I get an overlay stating a security error occurred.

    This has happened the last few times.

    Any ideas why and any ideas as how to fix it?

    It just worked for a file between 5-6MB...

    Do you have suhosin installed (hardened PHP)? Suhosin can truncate requests when limits are exceeded which can cause a security error like this if the token is truncated. Otherwise you would normally get an error saying what limit has been exceeded.

    It's working now, thankfully.

    I think it may have been the max post size? It was set to 8MB :/

    Also, you get a different uploading screen sometimes...
