I can confirm that we are using the most updated version of Ad Rotate Pro – 4.9.1. It seems like the second issue with the user-list table is unrelated, that’s fine. We only have one Dynamic group on the site, on the homepage. It looks like the issue is coming from the adrotate_impression action. Would this be resolved by tracking analytics in a different way, say through Google Analytics? https://ajdg.solutions/manuals/adrotate-manuals/google-analytics/ If not, is there any way to continue to use Dynamic groups with this plugin without resulting in this error? Thanks in advance!
