Problems with Bot "Nothing to do"

Im leveling a Dk which is level 92 and i have quest in my zone but it says all quest are done nothing more to do, i´ve tried both old profile 1-110 quest and new one and still the same, what should i do when this happends?

Sometimes i do a quest and it does two mores after it and go again Nothing to do

What should i Do?

I leveled my mage without all those problems..

Edit: I add a photo

 

Used The Cache clean and seems working fine now
