Installation error (500) - CS-Cart 2.1.1

I am in the process of installing CS-cart on my domain. As per installation manual I have unzipped files in the correct location and I have made necessary permission changes.



When I try to access the install/ folder I get an “internal server error”, where do I start troubleshooting?



Thanks for any help.

Actually I managed to fix it.



Rather than unzipping installation file locally and then uploading it, I have uploaded tgz file and I have extracted it on the remote server.



This fixed my installation problem.
