Hello
I am from Russia and I'm sorry for my English, but try to describe your problem.
Joomla 2.5.7 ARTIOSEF 4.2.9
Setting: Configuration -> Basic -> Use Title or Alias? (Full title and Title Alias)
URL included in the Category Blog Full title is:
URL: www.sayt / autonews / autonews
"autonews" - Menu Items Alias
"autonews" - Menu Items Alias
URL included in the Category Blog Title Alias ​​is:
URL: www.sayt / autonews / news
"autonews" - Menu Items Alias
"news" - Articles Category Alias

Possibly do to Category Blog URL like this:
URL: www.sayt/autonews/
or
new feature (never) to Use Title or Alias? (Full title and Title Alias ​​and Never)

If that is not clearly explained.

Here you can expect help from technical support, or I did not properly written?

Hi,
In Content extension parameters (accessible from Manage Extensions page in JoomSEF) on the Common tab, you can disable the "Add Menu Title to URL" to remove the first "autonews" part of the URL.

Hi,
Thank you!
Everything was so simple, but the reason to solve this problem could not :-( Thank you!
