There is many errors, but all of them are variable that have not been declared before using it, as example :

$style == 'flex' ? $flex_style = ' flex' : '';
$style == 'blog' ? $blog_style = ' blog' : '';

$blog_style = $output  = '<div class="sppb-addon sppb-addon-latest-posts'.$flex_style.$blog_style.' sppb-row ' . $class . '">';

In this case $flex_style and $blog_style are not declared, you should write this instead :

$flex_style = style == 'flex' ? ' flex' : '';
$blog_style = $style == 'blog' ? ' blog' : '';

That is just an example, but if you search a little you'll find other issue like this one.

Thank you! I think with this example I can solve most of the errors. And in the case of the error Undefined property: stdClass :: $ params? Can you give me some example of a solution? — Leonardo Nunes, Jan 19 '17 at 15:49
