Remove these ads? link is broken
The link to https://pluginize.com/plugins/custom-post-type-ui-extended/ref/pluginizeaff/?campaign=cptui-sidebar-remove is broken for me:
https://github.com/WebDevStudios/custom-post-type-ui/blob/7e65f7db64ec6c1ffb6c9512fd88cbe8449f1743/inc/utility.php#L363
where does it drop you on to? Just the base pluginize.com domain?
404

Interesting, will need to look into that because I didn't end up at a 404. The URL parameters are just meant to see where traffic comes from, so visiting the shop will be the next step if you're wanting to get rid of the ads and more hopefully the features of Extended are appealing :D
For future me, this is because AffiliateWP is deactivated. Waiting on feedback for how to approach.
Change to just link to https://pluginize.com/plugins/custom-post-type-ui-extended/
