Error with portfolio.php in extend folder from cornerstone plugin

[Estel]

I’ve been working on a site for a few days and all was going well. Suddenly i get this message:

Warning: in_array() expects parameter 2 to be array, string given in /home/serveisd/public_html/wp-content/plugins/cornerstone/includes/extend/portfolio.php on line 227

Warning: Invalid argument supplied for foreach() in /home/serveisd/public_html/wp-content/plugins/cornerstone/includes/extend/portfolio.php on line 241

I don’t know why and i haven’t got any idea of php.
How can i resolv it?

Hi Estel,

Please note that this is just a PHP warning and is not an error.

Kindly login through FTP then edit the wp-config.php file then edit the define( 'WP_DEBUG', true ); to define( 'WP_DEBUG', false );

Hope this helps.
