Call to undefined method lib\\core\\Session::regenerate()

Wappler: 4.5.1
OS: MacOS (Intel)
Server: PHP

This has been working for a while but seems to have broken in the last week or so.

I have a logout SC script with literally just that action in it:

I’m viewing the file directly in the browser and am getting this:

code: 0, file: "/home/site/dmxConnectLib/lib/auth/Provider.php", line: 104,…}
code: 0
file: "/home/site/dmxConnectLib/lib/auth/Provider.php"
line: 104
message: "Call to undefined method lib\\core\\Session::regenerate()"
trace: "#0 /home/site/dmxConnectLib/lib/auth/Provider.php(159): lib\\auth\\Provider->setIdentity()\n#1 /home/site/dmxConnectLib/modules/auth.php(64): lib\\auth\\Provider->logout()\n#2 /home/site/dmxConnectLib/lib/App.php(195): modules\\auth->logout(Object(stdClass), '', NULL)\n#3 /home/site/dmxConnectLib/lib/App.php(127): lib\\App->execSteps(Object(stdClass))\n#4 /home/site/dmxConnectLib/lib/App.php(94): lib\\App->exec(Object(stdClass))\n#5 /home/site/dmxConnect/api/Security/logout.php(8): lib\\App->define(Object(stdClass))\n#6 {main}"

I’ve published everything again and tried recreating the file but it keeps giving this error.

Any ideas?
