Hi,
I am a fan and I'm working with your template jf_calla_exteriors.
In the latest module in place I have included links to my articles, but I appear under the title of these errors:

Notice: Trying to get property of non-object in C: xampp htdocs arese modules mod_k2_content mod_k2_content.php on line 33

Notice: Trying to get property of non-object in C: xampp htdocs arese modules mod_k2_content mod_k2_content.php on line 35

I checked the file mod_k2_content mod_k2_content.php lines 33 and 35 and this is what I see:

line 33       $ itemCustomLinkTitle = (K2_JVERSION! = '15 ')? $ menuLink-> title: $ menuLink-> name;
     }
line 35    $ params-> set ('itemCustomLinkURL', JRoute :: _ ('index.php? & Itemid ='. $ menuLink-> id));

Could you help me to remove this error?

best regards

Thanks m.freak,
then when the site is uploaded to the server these "warnings" disappear right?

Upload your site and test it, that's configuration of your server.
