Well now I am confused, are you using Mys v1.3.2's code now? If your site is still a Mys v1.3.1 site, you need to replace variables beginning with $mysidia by their equivalent Mys v1.3.1 variables. Some examples are given below:
PHP Code:
$mysidia->user->username => $GLOBALS['loggedinname'];
$mysidia->input->get($param) => $_POST[$param];
$mysidia->input->post($param) => $_POST[$param];
$mysidia->page->settitle("") => $article_title = "";
$mysidia->page->addcontent("") => $article_content .= "";
$mysidia->user->isloggedin() => $GLOBALS['isloggedin'];
$mysidia->output() => echo showpage($article_title, $article_content, $template);
There is no counterpart of $mysidia->user->getstatus() in Mys v1.3.1 though, so you have to get rid of all code associated with them.
