LC Server - HTTP response code 500: permission denied error

[Martin Koob]

Hi Ralf

Thanks for your reply Ralf.

Based on your comments I tried a number of tests.


I tried an .lc  file with no calls to RevIgniter.

/home/myapp/sites/api.myapp.com/mylctest.lc

I get the same error as when my application calls the api using RevIgniter. So that means it is an issue with the server not RevIgniter.

lscgid: execve():/home/myapp/sites/api.myapp.com/cgi-bin/livecode-server: No such file or directory


To see if I could access a file in the directory I then created a plain html page and put it in the same cgi-bin directory as the livecode-server file

/home/myapp/sites/api.myapp.com/cgi-bin/mytest.html

that gave an error

lscgid: execve():/home/videolinkwell/sites/api.videolinkwell.ca/cgi-bin/mytest.html: Permission denied

I then tried the two tests on my existing server that I am migrating my site from.  Both the mylctest.lc file in the top level of the api.mysite.com and plain mytest.htmlfile in the cgi-bin folder loaded as without error.   So I have something wrong in the set up of the cgi-bin folder of the new server I am migrating my site to.

I then tried a couple of other things.

I copied the .htaccess from my old site and that had no effect.

I then looked at the permissions of all the files.
myapp.com 0750
	cgi-bin 755
		livecode-server 0755
		drivers 0755
			dbmysql.so 0644
			(and other drivers…) 0644
		externals 0755
			revdb.so 0644
			(and other drivers…) 0644
			
This is the same as my existing server except for the myapp.com directory which is 0750.  On the existing server it is 0755 so I changed it and tried again and I got the same errors.
It seems like a permissions/access issue but I am not sure what else could control that. I am sure it is something simple Any ideas?

Thanks again

Martin
