False Positive: Ticket shop for holidaypark.de not working

[d-Rickyy-b]

Hi, it's me again. Today I found out that the ticket shop for the German amusement park "Holiday Park" is not working, because they host a script for the webshop on googletagmanager.

They even write on their website (translated by Chrome):

But this is not about "outdated" versions. It's just that several filter lists block googletagmanager in general and hence also block there script at.

www.googletagmanager.com/gtm.js?id=GTM-M2XPLS9

(Peter Lowe's Ad and tracking server list, StevenBlack/hosts with the fakenews and gambling extensions, and this list, 1Hosts (Pro)).

But apart from that, some block lists also block another script file:

www.holidaypark.de/sites/default/files/public/google_tag/google_tag.script.js?qxo8te

I'm not sure if you want to fix this behaviour. I just wanted to report and let other people know how to fix this issue.

The workaround I implemented locally:

@@||www.holidaypark.de/sites/default/files/public/google_tag/google_tag.script.js?qxo8te$script,domain=www.holidaypark.de
@@||www.googletagmanager.com/gtm.js?id=GTM-M2XPLS9$script,domain=www.holidaypark.de

Cheers!

Got it! Related: https://github.com/uBlockOrigin/uAssets/issues/9368, https://github.com/uBlockOrigin/uAssets/issues/8918, https://github.com/AdguardTeam/AdguardFilters/issues/69692

Unfortunately, we only maintain dns/network blocking filters. Removing the GTM entry, especially from 1Hosts (Pro) is a bad idea. I recommend that manual removal be undertaken. Sorry!

No need to be sorry! I already assumed that adding exceptions for things such as GTM would be hard. At least we got it documented here for people googling for it. Thank you!
