Quantity change at product page

[sstucl]

Hello,

 

 

I'm having issue with product page, when I try to click + or - I get error message (site not available), but the value is changed. How can I get rid of that error message?

 

for example:

 

http://party.si/si/zabava-hawai/4460-hawai-zabava-hawai-slamnati-klobuki-crn.html

 

 

click on quantity on right -> + or -

 

 

Using 1.6.10 and default-bootstrap

 

Thank you!

You'd need to look at the server's logs to see what's causing the error in the back end.
