TOPIC: Joomla Comment & Joomla 1.0.15 not work

Joomla Comment v3.26 & Joomla 1.0.15 not work. I try with fresh install of Joomla 1.0.15 and another site with upgrade Joomla from 1.0.12. to 1.0.15.
On this site was two diferent template. 1 is Rockettheme - MediaMogul and 2 is YouJoomla template - innovative_lab.

Ver. 3.25 & Joomla 1..0.12 with MediaMogul template works fine.

Ver. 3.25 & Joomla 1..0.12 wit YouJoomla template - innovative_lab say :
" Internal Server Error The server encountered an internal error or misconfiguration and was unable to complete your request "

Any ideja ?

My development environment has 1.0.15 and everything works just fine. Can you give me an URL? Are there some error messages or so? Is the joomlacomment bot published?

Yes bot is publish. I have over 600 koments with ver. 3.25.
Tell my somethink. If my site is www.mydomain.com and i make copy of site www.mydomain.com/copy1 . Can i use the same SQL base?

If yes i make copy of site and give to you admin access. Site is live news portal and i can't make mistake on original site.

Well, what is the difference if you use the same database?
The path doesn't matter, but if you use the same databse, that means all the changes I make will affect the main web site.

I send you PM.
