"enter A Valid Date" Error In Django Forms Datefield

I know there are a lot of threads alredy talking about this but there is none that remotely solved my problem. This is really weird because everything has been done how it's meant

Solution 1:

Well, i don't know what to say... Maybe Django had a "caching" problem or something like that. Because there don't seem to be a scripting problem which just happen to solve itself (unless there's a 3035 year robot software around). If anyone has this problem, follow the answers on other questions here, like this one :
