Add Button sending me to index page

I try that way to but im having the same responses

Is your site www.lovebuglenceria.com/index.php ?

I tested "Add to Cart" button in several different browsers and worked fine everywhere, the same way as our demo works.

i found out that when i follow the link it works fine but it doesnt when i enter the url directly i was even thinking that could be some regional block or some thing like that i see that it is not because in several machines is working fine i dont know why in some other few it is not

Maybe absence or presence of

in url is problem. You can use htaccess to fix url's by rewritng, but first see it that is case.

It looks like that is the issue i tested and with out it doesnt work fine if added works fine on any browser the .htaccess is active maybe i have to unlock somthing thanks for the help identifiying this issue
