Language problem "0 _bx_ads_Ads"

Hello, i have big problem, please help!

in my site with FireFox, Chrome language is showing like this! " 0 _bx_ads_Ads" (MiniFilmas.lv) Please tell me whay? i'm using 7.07 beta 1 i think.

But with Opera all is allright! And one more question, how i can upgrade to 7.07 beta 2? without file (video) lose?

Thanks for help!

My guess is in Opera you are still looking at the site with English set as the language. In firefox you most likely have it set to Fescenia which is your other installed language which you have not fully translated. It also appears that you created that language before you installed all of the modules.

For proper translation refer to these instructions. http://www.boonex.com/trac/dolphin/wiki/DolLang

As for upgrades. The Betas are for TESTING ONLY. Not to be used in production sites as such there is no need to preserve data. No upgrades between betas are provided. If you intended to setup a production site you should have installed 7.0.6 which is the current version that is available.

No this is Original. 7.0.6! I think this is becouse i have i have instaled this on other domain and then just reinstall on new domain. 

And about Templates, you can change template and there is no diference.
