Hi Daniel,
Thanks for getting in touch with us, and sorry to hear about the issues after updating the plugins.
First of all, please downgrade the plugins to version 4.4.1.x were this was working correctly for you. After doing so (if links are not working) just go to ‘WP-Admin > Settings > Permalinks > Save Changes’. once the site is working correctly let’s test the update in a staging / dev site. Does that sounds good to you?
This might be something particular to your site. We are getting some reports of glitches after the release but still haven’t isolated any new bugs.
Please let me know about it,
Best,
Nico
