Hi kobra, thanks for your suggestion and I have actually done that. I have even reloaded the original content of tpl_main_page, tpl_main_page_default, index.php after deleting the html thread I have added in define_main_page and nothing really happens. It's really totally weird experience for me. Not only that I cannot clikced on product images but as well as the links in sideboxes are turned off. I have been searching an answer from different threads in the forum but seem cant get one. I hope you have an automagically answer for this , because you really have the touch in zen cart .

Thanks again kobra.....
