I Fill next fields respectively: Handler: python-program Extension(s): .py 5) Using my browser (chrome | IE) I was try to run my script by link: apiapi.heliohost.org/cgi-bin/hello.cgi 500 server error was occupied If my file extension is .py - just source code is shown as result 5) Also I try to fetch my script recuvest thru html-page: <html> <head> <title>script</title> </head> <body bgcolor="black" text="#FF9933" link="blue" vlink="purple" alink="red"> <form action="http://apiapi.heliohost.org/cgi-bin/hello.cgi">Enter: <input type=submit value=Go> </form> </body> </html> Result always is the same I do not know what to do...

mtpews Posted August 22, 2017 Share Posted August 22, 2017 Delete everthing thing (.htaccess, apache handler,....)and try use this: #!/usr/bin/pythonprint("Content-Type: text/html")print("")print("Hello") or this if the above doesn't work, but the above worked for my script. : #!/usr/bin/pythonprint("Content-Type: text/html")print()print("Hello") Remember to chmod the cgi-bin folder and the file to 755, not 644 nor 777, must be 755 to work.If you're using Python 2.x then remove the "(" and ")" Quote Link to comment Share on other sites More sharing options...
Krydos Posted August 22, 2017 Share Posted August 22, 2017 http://apiapi.heliohost.org/cgi-bin/hello.cgi is giving a 500 error because it is permissions 644, and it needs to be 755. Quote Link to comment Share on other sites More sharing options...
palaniza Posted August 25, 2017 Author Share Posted August 25, 2017 Thank You so much for your help Yes, of course permission for cgi-bin directory and hello.cgi file are set to 755. I perform every steps answered here but it still doesn't work. Following this linck: http://apiapi.heliohost.org/cgi-bin/hello.cgi 500 error is occurred Please, help my Quote Link to comment Share on other sites More sharing options...
Krydos Posted August 25, 2017 Share Posted August 25, 2017 Um. No it's not:root@johnny [/home/palyuri/public_html/cgi-bin]# ls -l total 4 -rw-r--r--. 1 palyuri palyuri 72 Aug 25 06:34 hello.cgi If it was 755 it would say -rwxr-xr-x. Right now it's 644. What 644 means is owner can read and write, group can read, and other can read. What 755 means is owner can read, write and execute, group can read and execute, and other can read and execute. You can change the permission through SFTP or with the file manager in cpanel https://johnny.heliohost.org:2083/frontend/paper_lantern/filemanager/index.html Quote Link to comment Share on other sites More sharing options...
palaniza Posted September 18, 2017 Author Share Posted September 18, 2017 Thank You so much for your reply Оh, exactly... I changed the permissions (to 755) on the file to. But the problem remains ((( http://apiapi.heliohost.org/cgi-bin/hello.cgi not work Please, help my Quote Link to comment Share on other sites More sharing options...
Krydos Posted September 18, 2017 Share Posted September 18, 2017 The next problem is you're using dos line endings on a linux system. Cgi is very particular about line endings. The easiest way to make sure you're encoding your file correctly and using the proper line endings is to use the cpanel filemanager, and then click edit code. Either that or you can use a windows editor that knows how to output linux line endings like notepad++. Quote Link to comment Share on other sites More sharing options...
