Recently upgraded to version 4.02. Banners are delivering properly but impressions are not recorded. On checking, I found 2 plugins with errors (Configuration > Maintenance > Plugins> Plugin Report).
oxDeliveryDataPrepare: Plugin is not yet installed oxDeliveryDataPrepare oxDeliveryDataPrepare: Plugin not installed vastInlineBannerTypeHtml: is configured as installed but not found to exist
I have tried re-installing them but the errors remain. Any advise please?
