Mini K2 unconfigures my template

Hello, I am a new user of Joomla. I use the version 2.5.8 and I recently installed the K2 Mini module. As soon as I turn it (without changing anything), my template stopped working, as if there were no CSS file.

My website is: arpiadesign.com/

PS: I tried disabling the other modules, but the error persists.
Sorry if my English is pathetic, but it is not my native language.

Hi LG2892,
Do you have any other K2 module installed on the same page?
What K2 version did you use?

Hi sikumbag,
I have not installed another module K2
I'm using version 1.2.1 for Joomla 2.5

Thank you.

PS: I tried another template and get the same error.

I'm using version 1.2.1 for Joomla 2.5

Sorry I mean what k2 version, not the minik2 version

Ready! I get it, as I said, I am new to Joomla. Did not know to install the component K2. Now my site works. Sorry for the inconvenience.

Ahh .. ok ... Glad to now it's solved now Have a nice weekend
