I was able to install sj hexagon, but before the Sj K2 Slick Slide module the following error appears:
Strict Standards: Non-static method K2SlickSliderBaseHelper :: _ cleanText () should not be called statically in /home/tocan924/tocantinsonline.tocantinseconomico.com.br/modules/mod_sj_k2_slickslider/core/helper.php on line 310
