OK, this is bizarre. I googled "5 Pocket Jean - 30 / Indigo $ 404.6 304.6" which is text that appears on the clothing site screenie I captured. google lists four sites as having that text: https://nutrakeyhealth.com/collections/daily-and-general-health https://nutrakeyhealth.com/collections/sale https://www.lotustrolleybag.com/apps/help-center https://rockrelentless.com/pages/rock-relentless-brand-warness Yet none of those sites sell Indigo jeans or have any pages that look remotely like the screenie I captured. When I loaded the rockrelentless.com site, I got that same flash of the Indigo jeans site. So somehow some site's code has become embedded in other sites and plays as a flash when the site loads. I'm too stupid in IT to know what's going on but it seems flavourworld.co.za is not the only site that is having this. Edit: and another site that plays the Indigo flash: https://coastalracks.com/collections/kayak-accessory I've attached a screenshot of another site, apricoat.com, where the same Indigo overlay shows on loading.
