What to do when the Automatic Blocking mode is blocking too much?
The automatic blocking mode will automatically block all scripts and iframes on your website, then check which have consent and will reactivate these. In most cases when there is a problem with the automatic blocking it is due to that the CMP could not identify a vendor for a certain script or iframe.
- Go to Menu > Vendors and verify that all vendors are in your vendorlist and that there are no vendors waiting for approval:
Please add all found vendors to your vendorlist:
- Go to Menu > Vendors and verify that all blocked domains are assigned to a vendor:
Please assign all necessary domains to a vendor:
More Information on assigning domains, please follow these steps in order to assign the unknown domains to the vendors. - Go to Menu > Vendors and verify that all vendors are assigned to a purpose:
-
Only for vendors that should never be blocked: Ensure that the vendor (or the purpose to which the vendor is assigned) is set to a legal basis that prevents the vendor from being blocked (for example "Legitimate Interests (no opt-out possible) (GDPR 6.1.f) [Always on]"):
- Ensure that you waited at least 30 minutes after you made changes. Some changes that are applied to the CMP settings may take up to 30 minutes before they become active on your website.
- Only if the above steps do not help: Specifically exclude blocked domains from the automatic blocking (see description below)
If the above steps are not sufficient, please use the CMP debugger console in order to find more details on which the scripts are blocked and why.
Alerting for unknown domains
Visitors on your websites may have malware or toolbars installed which inject code into the visited websites (usually advertising). If that is the case, the automatic blocking code might find domains that not actually installed on your website. You can simply ignore these domains.
Excluding scripts/iframes from automatic blocking
The easiest way is to use the CMP settings at Menu > CMPs > Edit > Other settings > Automatic blocking:
In some cases it can be necessary to exclude a script or an iframe from automatic blocking. In order to do this, please insert the attribute data-cmp-ab="1" or data-cmp-ab="2" (see here for the difference) into the script or iframe code. Example:
<script data-cmp-ab="1" src="https://..."></script>Blocking inline scripts
In some cases the automatic blocking code will block inline scripts and other elements on the page that are required. In this case you can adjust the automatic blocking code by inserting certain variables before the code. For example:
<script data-cmp-ab="1">
window.cmp_block_inline = false; //true = blocking of inline scripts
window.cmp_block_ignoredomains = ["domain1.com","domain2.net","domain3.org"]; // list of domains that should not be blocked
</script>For more details on how to configure automatic blocking see here.
