We have fixed your site template, now the extension should work fine.

Thank you, I am really happy now, I would like to know what you changed if possible.
And i have another small request, I looked in the settings but i couldn't find anywhere.
On the header of lightbox there is a white space which on your preview page looks black, i would like to have that black too.
Here is a screenshot attached.

Thank you for a great plugin

As we wrote in our previous mail your site template contained incorrect code for removing MooTools library, it removed all javascript includes which were done through Joomla! API. It could cause problem with a lot of other 3rd party extension, but we fixed this code. About background, you can define it, if add bgColor="#000" attribute to {arisexylightbox} tag or set default background in "System - ARI Sexy Lightbox Anywhere" plugin settings with help "Background" parameter.
