phoca gallery doesn't work

Hi, please see: der-eule-verlag.de/2013-11-08-11-53-34/b...ory/1-antiquarisches

If I try to open a picture I have the error message
500 - JHtml: :bootstrap not supported. File not found.

How can I make phoca gallery work propperly. All other gallery modules I tried out are not the quality according to phoca.

Why does phoca gallery work in for instance EVENT Template and not in BLOCKS?

Please don't tell me to upgrade to joomla to 3.xx. It's far to soon. I tried this. A lot of comps and modules do not work yet at all. If you know that bootstrap only fully works from Joomla 3.xx and higher, why do you use it in 2.5 Templates?

If you know that some of the most used comps or modules do no work in your template construction/programming I expect a warning of you bevor installing the system, not find it out myself long after the site is set.

Anyway, as good as your service is and even if this might not interest you, I am very angry.

Bootstrap is not part of joomla 2.5, that even has nothing to do with template. There are few plugins on extensions.joomla.org that claim to add bootstrap to joomla 2.5 . You can check them out
