i saw again RewriteEngin on. How many time can put this RewriteEngin on on my htaccess.
And this code can work with oxwall software. I have already switch on watchdog plugin also.

Thank
Best regards

Alix, have you checked the google search I provided you. 

I don't know whether this going to work, you can test it on your own, if it does not work, you can delete this code any time. 

No need to put RewriteEngine on two times. 

ok thank, i'm going to test that this week. I have al ready an htaccess code if this code can't make a conflict that cool for me.
But i thank Watchdog do his work as well for this moment. Only 2 pass
One time RewriteEngine is enough.... ok
thank
