Sinapp Theme Child Issues

Hello,

I’m a complete newbie when it comes to wordpress or making a website. I have been reading a lot on here about what I need to do to customize my website. I am making an app so I need to make a website for that app. I didn’t want anything that looked like the basic cookie cutter site and want it to stand out and look great.

Enough of the back story. I’m using Sinapp Theme and my problem is I created a child theme as suggested but now I cannot use the customization theme settings tab to change anything on the appearance (colors, texts, wording, email boxes, app store images, etc.)

I have since figured out how to find the code for the header and change that in my child to make the site title be my app’s logo.png and how to upload a different image with the same name of the parent theme image to upload the image I want instead. I can’t find where to change the text and background color I had put into the bottom section of the page before switching to child. I also see code in the functions.php file for sidebars, but the theme itself says it isn’t widget ready because it doesn’t have any sidebars. I can’t figure out how to change the coding to make them work? I really would like to be able to put a larger image of my ‘mascot’ on the left side of the page in the header area. Here is the coding below:

/*************************************************************/
        /************CHOSE SIDEBAR POSITION************************/
        /************************************************************/

        function tk_get_left_sidebar($sidebar_position, $sidebar_name) {

            $sidebar_option = get_theme_option('Inkland_general_custom_sidebars');
            if($sidebar_position == 'Left'){
                if($sidebar_option !== 'yes') { ?>

                    <div id="sidebar" class="left">
                           <?php if(function_exists('dynamic_sidebar') && dynamic_sidebar('Sidebar Default/Home')) : ?>
                            <?php endif; ?>
                    </div>

               <?php } else { ?>

                    <div id="sidebar" class="left">
                           <?php if(function_exists('dynamic_sidebar') && dynamic_sidebar($sidebar_name)) : ?>
                           <?php endif; ?>
                    </div>

            <?php }
            }
        }

        function tk_get_right_sidebar($sidebar_position, $sidebar_name) {

            $sidebar_option = get_theme_option('Inkland_general_custom_sidebars');
            if($sidebar_position == 'Right'){?>
            <?php
                $sidebar_option = get_theme_option('Inkland_general_custom_sidebars');
                if($sidebar_option !== 'yes') { ?>

            <div id="sidebar" class="left" style="margin-left: 30px">
                   <?php if(function_exists('dynamic_sidebar') && dynamic_sidebar('Sidebar Default')) : ?>
                    <?php endif; ?>
            </div><!--/#sidebar-->

               <?php } else { ?>

            <div id="sidebar" class="left" style="margin-left: 30px">
                   <?php if(function_exists('dynamic_sidebar') && dynamic_sidebar($sidebar_name)) : ?>
                   <?php endif; ?>
            </div><!--/#sidebar-->
            <?php }
             }
        }

Sorry if this is a jumbled up post, I have so many questions! I have wasted an insane amount of time trying to figure this all out on my own, not wanting to bother ppl with trying to help me. But, here I am, begging for help.

Thank you!`
