[ Moderator Note: Please post code or markup snippets between backticks or use the code button, not the blockquote. ]

function add_checkbox()
    {
        $options = get_option($this->widgetOptionsName);
        ?>
        <p>
        <input value="1" id="aweber_checkbox" type="checkbox" style="width:inherit;" name="aweber_signup_checkbox"  />
            <label for="aweber_checkbox">
            <?php echo $options['create_subscriber_signup_text'];?>
            </label>
        </p>
        </br>
        <?php
    }

add the following inside

<input />

checked="checked"

so it looks like

function add_checkbox()
    {
        $options = get_option($this->widgetOptionsName);
        ?>
        <p>
        <input value="1" id="aweber_checkbox" type="checkbox" style="width:inherit;" name="aweber_signup_checkbox" checked="checked" />
            <label for="aweber_checkbox">
            <?php echo $options['create_subscriber_signup_text'];?>
            </label>
        </p>
        </br>
        <?php
    }

I have implemented the code but still not working.

paste the entire plugin code so i can see if you did it right

MrFent37, Thanks a lot for your help.

My Issue got resolved as I bought premium plugin (Subscribers Magnet) for this task.

PS: Your code was also working fine later. I am using CDN on my blog so changes were not reflected at that time.

You help was much appreciated.
