MiniK2 Module loading problem on my portfolio page

I have installed MiniK2 module but the page doesn't load. It shows some errors. I have provided you the admin access. The portfolio page link is given below:

dezigneronline.net/dev/index.php/portfolio.html

Right now the development mode is turned on. I resolved all of these issue on my localhost except

Strict Standards: Non-static method modMiniK2Helper::getCategories() should not be called statically in /home/dezigner/public_html/dev/modules/mod_minik2/mod_minik2.php on line 198

But couldn't get the solution yet.

P.S.

I first tried to install TZ Portfolio on the same site but it didn't work too and showed following errors in google chrome inspector:

Uncaught SyntaxError: Unexpected token
Uncaught SyntaxError: Unexpected end of input

TZ portfolio worked well in another website but its not working on my website. After spending couple of days on TZ Portfolio, I started working on MiniK2. Now I am facing some other issues

So, I think there is a script that is conflicting with MiniK2.

Waiting for your reply.

Ok can you try to edit this file /modules/mod_minik2/helper.php

at line 580 please change it to

save it and see if the error is gone.

Thanks for your reply.

I found following code at line 1159 in helper.php instead of line 580 (please find the attached screenshot).

function getCategories(&$params)

and change it to

public static function getCategories(&$params)

But page is still not loading.

Mmm it looks to me your K2 is a bit old....can you please upgrade it first to the 2.6.x version...and see if that helps

Wow.

It works perfectly after upgrading K2

Awesome

Thanks very much.
