Script is not working on https://www.welt.de/

There is a Popup with an error and the site is not loading.

Using AdGuard on iOS (Safari) and the Userscript (3.2.1) installed via the iOS App „Userscripts“.

With AdGuard and Userscript:

Without AdGuard:

Did you read the pinned issue? #38

[mOrbo-git]

Actually not, thanks. If it’s because of a memory limit, would it help to clear all entries in the script, except for welt.de and install it as a custom script?

Yes.

Thanks, I deleted all websites in the script except welt.de. After uploading the script to a webspace and reinstalling it, welt.de is now working again.

tinyShield.user.js

[mOrbo-git]

I have to revert my answer. It worked yesterday, but today the error message appears again.

I think they changed something from yesterday to today. Now it does not work with the cleared script with only 4 entries. I don’t think this has anything to do with the memory limit anymore.

I’m using this version and the popup still comes up. The site welt.de is not usable anymore:
tinyShield.user.js

With AdGuard for iOS (AdGuard Base, AdGuard Mobile Ads, AdGuard Tracking protection and AdGuard German filters list only; no DNS filters lists; AdGuard non-filtering DNS server upstream used).
To reproduce any Ad-Shield issue at the website for me, connecting to AdGuard VPN for iOS is required. Disabling AdGuard VPN makes that Ad-Shield is disabled.
Only I confirmed https://welt.de/ only.
