How to remove "Powered by WordPress and Hostmarks" from footer?

I had same problem. This is how I resolved.

Open your web page and view code using inspect element (Firefox). On the left side of bottom window, there is a menu just in the left of menu. It says: “pick an element from the page” when you scroll your pointer on it. Click on it, and it should turn to blue. Then, select the block containing your WordPress and Hostmarks ads. For my case the code was something like:

<div class="col-md-12"> 
                        <?php echo __('&copy; ', 'wp-newsstream') . esc_attr( get_bloginfo( 'name', 'display' ) );  ?>
                        <?php if(is_home() && !is_paged()){?> 
                            <?php _e('- Powered by ', 'wp-newsstream'); ?><a href="<?php echo esc_url( __( 'https://www.ads-software.com/', 'wp-newsstream' ) ); ?>" title="<?php esc_attr_e( 'WordPress' ,'wp-newsstream' ); ?>"><?php _e('WordPress' ,'wp-newsstream'); ?></a>
                            <?php _e(' and ', 'wp-newsstream'); ?><a href="<?php echo esc_url( __( 'https://hostmarks.com/', 'wp-newsstream' ) ); ?>"><?php _e('Hostmarks', 'wp-newsstream'); ?></a>
                        <?php } ?>
                        </div>

The very first line

<?php echo __('&copy; ', 'wp-newsstream') . esc_attr( get_bloginfo( 'name', 'display' ) ); ?>

is to put your blog name on footer. So if you want to keep it, don’t delete it.

To remove ads, you should remove this part:

<?php if(is_home() && !is_paged()){?> 
                            <?php _e('- Powered by ', 'wp-newsstream'); ?><a href="<?php echo esc_url( __( 'https://www.ads-software.com/', 'wp-newsstream' ) ); ?>" title="<?php esc_attr_e( 'WordPress' ,'wp-newsstream' ); ?>"><?php _e('WordPress' ,'wp-newsstream'); ?></a>
                            <?php _e(' and ', 'wp-newsstream'); ?><a href="<?php echo esc_url( __( 'https://hostmarks.com/', 'wp-newsstream' ) ); ?>"><?php _e('Hostmarks', 'wp-newsstream'); ?></a>
                        <?php } ?>

Open style.css and remove this block from it. Take a backup of file before editing. It should be good/
