Internal Server Error

[autodrive18]

Hello,
I'm migrating my site to your hosting, but I'm having problems. A single folder works properly when I browse the site and I change the folder, I have the following message:
"The server encountered an internal error or misconfiguration and was unable to complete your request.
Please contact the server administrator, no-reply@x10hosting.com and inform them of the time the error occurred, and anything you might have done that may have caused the error.
More information about this error may be available in the server error log.
Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request."
I want to say that this file is working properly to another host.
Username: courtill
Domain: les.courtilles.x10.mx
Package: adfree-infinity
Hosting Server: starka
Thank you to explain the dysfunction

Check that your files and folders have the proper permissions - 644 for files and 755 for folders. If anything is set to 777, the server will block access with a 500 Internal Server Error message.

my files and folders have the proper permissions - 644 for files and 755 for folders.
And the problem is still present.
Folders concerned :
http://les.courtilles.x10.mx/Admin/
http://les.courtilles.x10.mx/Invi/
http://les.courtilles.x10.mx/Insp/
http://les.courtilles.x10.mx/Secr/
http://les.courtilles.x10.mx/Sous/

Only the following folder works correctly:
http://les.courtilles.x10.mx/Cond/

I copy a page of this folder, and that works corect.
I paste it into any folder above and it does not work!!

The problem is not the page, but access to the folder who contains.

Now when I type http://les.courtilles.x10.mx, I go ala index.php page.
But if I write directly http://les.courtilles.x10.mx/index.php, I again "Internal Server Error" as an error.

Check each folder for .htaccess files.

Print the contents here.

I do not have .Htaccess file in these folders.
The server seems unstable. Sometimes I get a page posted, if I update the page with F5 for instance, I get the message: "Internal Server Error".
