Method NullPage::isDefault does not exist or is not callable in this context (in /wire/core/Wire.php line 320)

All of a sudden I get this error:

Error: Exception: Method NullPage::isDefault does not exist or is not callable in this context (in /wire/core/Wire.php line 320)

This error message was shown because you are logged in as a Superuser. Error has been logged.

 

PW 2.3.2 (latest dev version).

I have no idea what that means. Strangely enough, it used to work. I just do

echo $page->sidebar

nothing fancy there...

Seems like it's an issue with your language settings.

There is an error with this part of FieldtypeDateTime.module

$this->user->language->isDefault())

Edit: Basically, $this->user->language is returning as a NullPage.

That error seems to indicate that the system has language support installed (i.e. there is an $languages API variable), but the user's language is not set. That's unusual for it not to be set, so I would check in your code to make sure you aren't manually setting $user->language to an invalid value somewhere.

Thanks. I stumbled over a stupid oversight, where I called the default language by name ("de"), rather than "default" or some such.

But with the wonderful new 2.3.2 multilang handling, all this has become obsolete

I just somehow ran into this problem and find no way to fix - besides importing and old DB backup (probably).

What did I do?

Within that instace I installed a second language for testing purposes, edited the homepage so that it has /de/ (default) and /en/ (second language), changed the Languages Support - Page Names settings to redirect to the default language path (/de/), created some pages, tested, felt fine with it.

Somewhere in-between I updated to the latest 3.0.190 dev and tested a bit more, did other stuff (frontend only, no API code or module dev), then deleted the second language and wanted to the change the homepage again... so here we are.

All other pages with (former) additional content in another language work fine, can be edited and whatsoever. The main difference seems to be that the homepage contains a repeater matrix field with content that's only available in english (second language I deleted now).

I always thought deleting languages is enough... maybe it isn't.

 

Someone any ideas?
