Our customer service team needs a talented and enthusiastic new member to deliver pre and post-sales assistance to WHMCS users. If you enjoy interacting with people from all around the world, find rapid change exhilarating, and taking the weird and wonderful in your stride, this is your job!
One of the brand new modules in version 7.4 introduces integration with Hipchat and Slack to send real-time notifications to your existing collaboration apps. During the pre-release testing we want to hear about your experiences with the module
the community? you make it sound as though there are a group of developers just waiting to help you for free... looks around...

are you looking at the same system that set the emails - not an old/backup/legacy system ?
for one of the clients affected go to their summary page

tblinvoiceitems for that invoiceid
is it missing from both ?
