[Answered] Php Code Is Not Working In Johnny

[souvikdgp]

Hi,

 

I have a page which takes a domain name as input and then tells user about the mata tags of that domain home page.

 

To do I used curl and PHP.

 

It was working fine until today. Since today morning it returning blank page. no error nothing.

 

Can someone please help?

 

My website is hosted in Johnny server.

is there an error_log file in the directory of this script?

[souvikdgp]

No.There's no log file. i tired to add error reporting by using

 

ini_set('display_errors',1);

error_reporting(E_ALL);

 

in my code. But even then nothing is logging. It was working fine till yesterday. Since today morning I am watching this problem.

That is odd... Could you include a link to the page? I should have asked this earlier.

I just checked and curl is working fine on the Johnny server. Can you post your basic curl code?

You can see nothing is reported here. A blank page is coming.

 

Let me know if you need any further help.
