Hi all!
My host updated the php version from 4.3 to 4.4. Now i'm getting al kinds of errors on my site like

Strict Standards: Non-static method GKIS_AppsProTech_Image::createThumbnail() should not be called statically, assuming $this from incompatible context in /home/femei-universitare/public_html/modules/mod_image_show_gk4/styles/gk_appsprotech/controller.php on line 54 Strict Standards: Non-static method GKIS_AppsProTech_Image::checkCache() should not be called statically, assuming $this from incompatible context in /home/femei-universitare/public_html/modules/mod_image_show_gk4/styles/gk_appsprotech/class.image.php on line 50 Strict Standards: Non-static method

Please help me!
My site: femei-universitare.ro

P.S. I've put error reporting in joomla to none and nothing happened

I don't see any errors on your site.
Those was errors or warnings?
