Hi everybody!
As titled - when I click on chosen product what I get is just a name of the product. Click any of these: http://www.justhdr.pl/index.php/hikashop-menu-for-products-listing.html
or try this: http://www.justhdr.pl/index.php/hikashop-menu-for-products-listing/product/4-free-goodie.html
Any idea what's wrong?

Hi there,

You have a 500 error. Could you please turn on the debug mode in joomla and set the error report to maximum in your backend configuration? It should give us more information about the error you get.

Thanks for quick answer!

This is what shows when 1st product (no image) is clicked:
Fatal error: Call to undefined function ImageCreateFromPNG() in /var/www/joomla/administrator/components/com_hikashop/helpers/image.php on line 790

For products 2-6:
Fatal error: Call to undefined function ImageCreateFromJPEG() in /var/www/joomla/administrator/components/com_hikashop/helpers/image.php on line 787

Which of Joomlas diagnostic info from the bottom of the page do you need?

Yet another info: Joomla+Hika are setup on fresh VPS server. When editing product info "The PHP GD extension could not be found" shows up (that's why I removed images for 1st product to test it).

Hi,

Yet another info: Joomla+Hika are setup on fresh VPS server. When editing product info "The PHP GD extension could not be found" shows up (that's why I removed images for 1st product to test it).

Any tips on how to install GD? Other forum thread etc.? It's VPS server, haven't asked OVH yet but I suppose they'll tell me to do it myself.
Shouldn't product #1 fire normally (no images in it) or standard Hika image is the problem?

It will depends on your server configuration so we won't be able to help you, that's why, asking it to OVH is the best solution.

Will do. Thanks!
