Issue posting mod to workshop : InvalidParameter

[Armise]

Hi, i've been trying to post my mod on the steam WorkShop from the SDK, but it didn't work.
Here's what it said :

Attempting to upload Mymod.civ5mod...
Uploading Mymod.civ5mod... SUCCESS
Filesize - 8760
File Persisted - True
File Timestamp - 1487020012

Attempting to publish file...

Steam Workshop Result : InvalidParameter

Cleanup success!​

The attempt to publish file takes about 2-3 seconds.
What is the problem ?

Before anything else, try changing your mod's title to something more unique. There might already be a mod uploaded to the workshop called "Mymod", and this might be causing problems.

Usually when I've heard of people having this problem it is because a mod's title is too long or is using special characters the workshop refuses to handle. But "Mymod" would not cause either of these unless there's a problem with a mod already uploaded with the same name.

It's also possible one of the files in the mod is corrupted or the images you are trying to upload to the workshop mod page are improper (not actually formatted correctly, too large, etc.).
