The appearance-customize page won’t open.

Hello Team,

The critical issue appears every time I try to open the appearance-customize screen. I’ll speak with WordPress.com, and they will resolve the issue.

Just as a test, I deleted this function from the file on the staging site that we created while testing this, and that was enough to fix the problem.

    /**
    * Update Shop page grid
    *
    * @param  int $col Shop Column.
    * @return int
    */
    public function shop_columns( $col ) {

        $col = astra_get_option( 'shop-grids' );
        return $col['desktop'];
    }

There won’t be any problems on the website if I remove the code mentioned above. Please verify with us.
