It's not BS. There is a size limit and if you are above it you cannot upload.
Your options in this case is to:
- Ask support to increase your upload limit, which they may or may not do depending on criteria we do not know.
- Use less space
- Use a third party upload site
The file size limits are, as of last time I checked:
Standard web | 1 GB |
Butler | 2 GB |
Standard Increase | 4 GB |
Non standard increase | 5+ GB |
The standard increase is given to anyone that asks for it, the criteria for the non standard increase is unknown but believed to be difficult and being granted one is a privilege that should not be taken for granted.
