statistic plugin ?

[mvlcek]

Can i display the internal reference side if i have multi language website ?
Like: server.tld/de/ server.tld/en/ etc.

I don't understand, what you want to do where?
The hits are counted per page, e.g. you get a count for index and another count for index_de.

And is it possible to reset the hitcounters and logtracks over the admin panel ? Or which files i must delete to do that manual?

Just delete all files in /data/other/hitcount and /data/other/hitcount_index.
