I'm getting this issue after updating to 2.1.9

Zhaan

Hi! I just updated to 2.1.9, and I'm seeing this blank/unstyled page when I try to create a new discussion:

Any idea what's wrong? o-o

I've disabled all plugins and tried diff themes.. nothing helped.

Maybe files are corrupt? Try to re-upload all the files.

Now it says:

New Discussion

Fatal error: Call to undefined method CategoryModel::GetByPermission() in /var/www/vhosts/testsite.com/httpdocs/library/core/class.form.php on line 256

I also cannot edit any users or usergroups now..

Did you create a backup before updating?

Zhaan

I did yes. Why, is this a problem that can't be fixed without reverting? o-o

Anyways, this is the piece of code mentioned in the error message:

// Grab the category data.
if (!$CategoryData) {
$CategoryData = CategoryModel::GetByPermission('Discussions.View', $Value,
GetValue('Filter', $Options, array('Archived' => 0)),
GetValue('PermFilter', $Options, array())
);
}

Delete all ini files in /cache

Run /utility/update

Try again

Zhaan

@R_J Done, but it didn't change anything

Maybe files are corrupt? Try to re-upload all the files.

What do you know, that solved it. I feel silly now.

Thank you kind sir!

partial upload is prime suspect, when missing core methods.
