I’m probably missing something pretty basic here, but I’m kind of lost at what I should be looking for. Obviously, the `page` variable is undefined but where is it actually used in this blueprint (`site.yml`)? ```auto title: Site columns: - width: 1/3 sections: fields: maintitle: label: Header main title type: text required: true width: 1/2 subtitle: label: Header tagline type: text required: true width: 1/2 menu: type: structure fields: label: label: Item label type: text help: If not set, the linked page title will be used width: 1/2 url: type: pages label: Internal URL max: 1 width: 1/2 introduction: label: Index introduction text type: textarea buttons: false required: true - width: 1/3 sections: pages: type: pages templates: - about - home - default - experience - notes - width: 1/3 fields: socials: label: Social networks type: structure fields: label: label: Label type: text url: label: URL type: url ``` ---

I don’t know what’s causing the error, but there’s something wrong with your template: The fields sections is missing the fields key: ```auto sections: fields: fields: maintitle: label: Header main title type: text required: true width: 1/2 subtitle: label: Header tagline type: text required: true width: 1/2 ``` Apart from that, maybe there is an error in a template? ---

No dice unfortunately. I even tried going back to basics and skip the columns all together: ```auto title: Some text fields: .... ``` It’s fully possible that there is an error in a template somewhere but I can’t see anything obvious, not errors are being shown with the `debug` flag active. Is there any way of getting a more thorough error in the panel? I can’t see anything particular in my localhost error logs either. ---

Is there anything in the browser console maybe? ---

I’ve had a chance to dig around some more and it seems to be related to that as well. If there is a `$page` undefined in the plugin, why would it throw that in the panel but not “on the page”? ---

That’s a good question, maybe it only throws a warning on the frontend but not a fatal error. The more interesting question is why it is somehow called in the Panel in this context- ---

I actually remade the plugin, which was based of the example `gallery` included in the starter kit, and the error is gone. I’m not quite sure what I did wrong the first time, only difference is I cleaned up the indentation in the `index.php` file. For all I know it might as well have been a weird cache issue? I’m still curious as to why it was shown in the panel though.
