Finally, got a solution to get rid of this problem. This would occur when you have started a ad with a specific daily limit, for example if you set a daily limit of says Rs 250 and your total ad budget say (Rs 1250 for 2 weeks). Once this is ad is completed and reached the earlier specified daily limit, the ads will stop running. In such scenario, do the following
- In the Facebook account, Click on Billing
- In the Billing summary page, after "Account spend" there is link "edit"
- Click on "edit" and increase the amount
- The ads will start working
You're near the account spend limit you set for <123412341234>. Once you reach your limit, ads in your account will stop running. Reset the spending cap by visiting the account billing page.123412341234>
