I get 2 warnings if I show the main page in the browser. First is: "Warning: "continue" targeting switch is equivalent to "break". Did you mean to use "continue 2"? in G:\xampp\htdocs\GWRE_NEW\templates\gwre_new_template\functions.php on line 180".
Second is: Notice: Undefined offset: 1 in G:\xampp\htdocs\GWRE_NEW\templates\gwre_new_template\library\Artx\Content\Item.php on line 68

My template was created with Version 4.3

Can an ybody help me?
