Dear Sir/ Madam, The quiz series is automatically ending…

Hi Narayan,
I’m guessing you are using ads? If so, your ads are running in Google’s “automated” mode – this means that GOOGLE chooses where the ads are placed and we have zero control over this. If Google decides to place an ad in a poor area, then it can potentially break the HTML markup that HD Quiz needs to do things like pagination. I cannot know or help further without seeing a link to a quiz though.
