When using the IP information tool, the links to global contributions and XTools do not work. They include "null" instead of the IP.
Examples:
- https://nl.wikipedia.org/wiki/Speciaal:Bijdragen/91.183.203.178 links to https://xtools.wmcloud.org/globalcontribs/null and https://xtools.wmcloud.org/ec/nl.wikipedia.org/null
- https://en.wikipedia.org/wiki/Special:Contributions/2601:589:4281:B780:A038:2EC1:4C51:2CC2 links to https://xtools.wmcloud.org/globalcontribs/null and https://xtools.wmcloud.org/ec/en.wikipedia.org/null
To be able to see this, make sure to enable the IP Information beta feature in your preferences.
Instead of "null", it should be the actual ip adress. Then, the link works as intended.
