I end up with an error after addin->saving the page. Where the page should be created and edited I get:
Error: Call to a member function of() on a non-object (line 665 of /*/wire/core/Page.php)
I'm not sure why this doesn't work. Cross link to issue report on dev ryancramerdesign/ProcessWire#892
I once deleted all users, but recreated them and set the created user id in db to be admin again. But since this is on creating a new page I don't know what's up. Kinda would be great to fix this as I need DynRoles for this project. I'll also try to search.
PW 2.5.19 where you already changed something there, but still get this error.
