Make Ads to not expire until deleted by owner.

Hi guys,

I tried to increase the lifespan of my ads but when i put in more than 90 days it didn't seem to like it and it caused problems. 

Is there a simple way i can make the ads last forever until deleted?

Thanks in advance.

How can I make the changes?

Thanks
