Internal Server Error - Help!

Hey, I’m new to all of this and I did a Cloud for myself.

After two days of creating a cloud, i got this problem:

Internal Server Error
The server encountered an internal error and was unable to complete your request. Please contact the server administrator if this error reappears multiple times, please include the technical details below in your report. More details can be found in the server log.

What do I have to do, that I don’t have this problem anymore?

Help me please

what are you trying to do when you get this message?
I am having the same issue while trying to download all contents from a folder.
It seems to be related to the fact that NCP cant manage to zip files cumulative size bigger than 2GB.
Is it the same you have?
