503 Service Unavailable Magento 1.9

[vartika_sharma]

Getting 503 Service Unavailable error only on the product details page, all other pages are working fine. I tried removing cache, sessions but doesn't work. I searched for the issue and found that the problem can be resolve by removing maintenance.flag but this file does not exist in my root directory.

So what else can be the issue?

Hi @vartika_sharma 

Add following line in the index.php file at the root folder.

ini_set('display_errors', 1);
ini_set('display_startup_errors', 1);
error_reporting(E_ALL);

Check product details page again if you received any error.

Or try once after removing var/cache folder from root.

Might be it help you!

Hello @Vimal Kumar 
Thank you for your response. I tried these solutions already but it only shows blank screen on frontend and even logs don't have any related errors

@vartika_sharma is there any public url for this.

So that we may have a look on to it.

Thanks
