Modal Window on page load

Hi,

I’ve been working with this theme for some time now and really enjoy it. I have however, run into some issues recently with the popup modal window appearing on my client site. This was not something I installed and so had to go through and clean the site, replacing all the files and rolling back the theme to an older version to remove the modal window and the corrupt files.

I have tried to find the specific code that is creating the pop up but I am not that familiar with code generally (I believe it’s in the javascript). Can you advise me as to what I should be looking for in the theme files. Where should I look and what exactly am I looking for to remove the popup?

Thanks,
Jackie
