Error on upgrade!
<Fatal error: Call to a member function getPermissionKeyByHandle() on a non-object in /home2/normacoi/public_html/normainfotech/concrete/core/models/permission/response.php on line 53>
I upgraded from 5.4.1 to the latest available through simplescript in my hosting with bluehost.
Kindly give a rescue action, many thanks in advance!
Many of the add-ons which were used for 5.4 no longer work in the versions 5.5+ which requires you to upgrade those too.
I also suggest upgrading by replacing the /concrete folder on your hosting instead of upgrading through a script just to avoid unneeded crap on your server, by using a script you keep the old versions cores too which basicly do nothing but take up space.
