XF 1.2 Security error when uploading largish attachment?

[Liam W]

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...

There are various PHP configuration values you may need to change: https://kb.mediatemple.net/questions/1117/How+do+I+increase+the+PHP+upload+limits?#gs

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...
