Hi Nick,

From the error you have provided, its seems like the PHP version on your domain is not compatible with the site code/function.

Can you please let me know the site PHP version by adding the below file to public_html folder or asking to your host.

> Create phpinfo.php file in /home/user/public_html folder

> Add the below code to phpinfo.php file

<?php phpinfo(); ?>

> save and close the file.

In browser access the url domain.com/phpinfo.php which show the PHP version on your domain.

Hi Shaan,

The PHP on my domain is 7.0

Hi Nickk,

So it is perfectly clear now.

mysql_* functions were removed as of PHP 7.

It is not recommended to use the old mysql extension for new development, as it was deprecated in PHP 5.5.0 and was removed in PHP 7. It is recommended to use either the MySQLi or PDO extensions.

You can seek the help of a developer to rewrite the site code to make it compatible. Or one of the easiest ways to fix the error is downgrading the PHP version.

Please try downgrading your PHP version from 7.0 to lower version and check the site.
