    Hey there Laurent_C,

    How are you doing today?

    These are mostly notices and you shouldn't worry too much about them now, "Deprecated: Methods with the same name as their class will not be constructors in a future version of PHP" is just saying that in future PHP will not support constructors that are not called "__construct", they are supported now so this is not affecting the functionality of your site in any way.

    If you just want to hide them on the front end of your site then you could either turn debug off in your wp-config file that is located in the root folder of your WP install by changing this line:

    define('WP_DEBUG', true);

    To this:

    define('WP_DEBUG', false);

    If you already have that set to false you can simply log these errors to into debug.log file and hide them on the front by adding these two lines in wp-config file:

    define('WP_DEBUG_LOG', true);
    define('WP_DEBUG_DISPLAY', false);

    Make sure that the above two lines are added above the:

    /* That's all, stop editing! Happy blogging. */

    Let me know how that goes

    Cheers,
    Bojan
