Question

First of all : I DID go through StackOverflow looking for answers, found some, but NONE worked. So here it goes again

I have this little Django project, sent it to an EC2 but I get the TemplateDoesNotExist: 500.html.

The thing is , at least for GET page, this shows up every 2 or 3 clicks ( redirects) , and when I F5 the page for 2, 3 times, it shows up again.

The file IS THERE, it just seems Django/EC2 wont look at it every now and then

I tested with debug both false and true, also tried TemplateDirs with relative, absolute and even both paths.

I tried almost everything i could find , and I am accepting every kind of solution too. BTW, i think my email is there, so, if you think is best to email me something, just do it, I would really apreciate it

Here is some code. Setting.py

Answer 1

When in production mode(debug == False) django expects you to have at the root level
of your template folders a 500.html and a 404.html

So I guess an error/exception is happening and django tries to raise a 500 page, but can’t find your 500 template.

Do you have these templates somewhere?
