Well, you can open the file template.tpl in your theme(main is the default) folder, and find this part:
PHP Code:
</td></tr>
<tr><td colspan="2" id="footer">{$footer}</td></tr>
Add HTML to the left or right side of {$footer} will append or prepend your custom footer information to Mysidia's default footer. An example is provided below:
PHP Code:
</td></tr>
<tr><td colspan="2" id="footer">
{$footer}
<br>
My own footer information
</td></tr>
Alternatively you can change the file /classes/class_footer.php directly, by modifying this method:
PHP Code:
protected function setCredits(){
$mysidia = Registry::get("mysidia");
$this->credits = new Paragraph;
$this->credits->add(new Comment("★ Powered by ", FALSE));
$creditsLink = new Link("http://www.mysidiaadoptables.com");
$creditsLink->setText("Mysidia Adoptables v".Mysidia::version);
$this->credits->add($creditsLink);
$this->credits->add(new Comment("★"));
$this->credits->add(new Comment("Copyright © 2011-2013 Mysidia RPG, Inc. All rights reserved."));
$this->setDivision($this->credits);
}
It is not the desired approach though, and you need to make sure to keep Mysidia's credit information unchanged.
