Need to post large attachments

[mryoshi]

I am using VB 3.6.7 PL1, I am also fairly new to VB modding

I need to enable posting of very large attachments. They will be as large as 500 MB.
This is not a public or high traffic board so I am not worried about bandwidth.
I switched my attachments to be stored in file system, in the admincp.

I am stuck on what to do next. I have the extensions added of the file types I want to upload, i set them to no maximum file size.
When I try and upload a large attachment it gives me an error.
"invalid Post specified. If you followed a valid link, please notify the administrator"

PLEASE HELP!!!!

Instead of a blank filesize setting, use a very high one.

I tried that. It still had no effect. Someone told me there is a setting in one of the config files I need to change I just dont know which one...

I'm guessing they're referring to php.ini (the PHP configuration file). You would have no access to this file on shared hosting. If you do have access to this file, you will have to change the max_upload variables to allow for a big filesize.
