I've posted about it in the moderators' forum, and I also suspect that some ads are being added or adjusted, as I'm not getting the pop-ups (I have advertising switched off, and will switch it on and see what I get).Originally Posted by Skippymjp
If it's any help. The advertising banner that's between the page header and the forum won't display until you've acknowledged the "test" popup. They may be related somehow.
ETA: I'm getting them when I switch the advertising on, and adjust my browser to allow pop-ups, so some changes are apparently being made to the ads.
Sorry about the inconvenience. There's nothing I can do about it, but I'm sure whoever is making the adjustments will resolve the matter as quickly as possible.
