Thanks for your reply but I am well aware of users, groups, permissions etc problem is that as soon as I change the /media/ folder permission to anything else (beside 777) my website becomes unaccesible with this error:
"!JoomlaComment template not found: mydefault"
All folders made by !JoomlaComment are asigned to user "nobody" and I cannot change that
I am again over and over very confused about this situation and I dont know how to fix it
Hint.. all folders in /media/ have 755 and in myjosctemplates/mydefault/css/ and myjosctemplates/mydefault/index.html have 644
FIXED in someway !!
Well, I've installed Joomla xplorer and I was able to overwrite some files from components /com_comment/bla/bla/bla/templates/MTdefault/
It would be great if after we customize our own template we can have an option to save that template in /templates/ folder .. otherwise in my particular case I was loosing 1 day and a half trying to find a solution.
Anyway, this component rock, its fast & reliable, have everything that I need but there's some issues that should be fixes in next releases..
I think that most of the problems appeared during installation when all folders where made unde "nobody" user&ownership
