Advanced settings: AttributeError: attribute app_title not found

[MacLake]

Summary

When I open the advanced settings of a CMS page, it doesn’t work with some user accounts: On the production site I get an AttributeError: attribute app_title not found while rendering the template admin/includes/fieldset.html. On the production site the advanced settings usually show up, but always incomplete, ending with the redirection field, but I can’t configure app hooks. Whether the issue occurs or not, depends on the user account: With my admin account and a colleague’s account we have this problem, with a test account and another colleague’s account the advanced settings do open normally, i. e. completely.

Environment

• Python version: 3.7 (development), 3.5 (production)
• Django version: 1.11.21
• django CMS version: 3.5.2, 3.6

Somebody else has reported this issue on Stack Overflow, but there wasn’t an answer.

Also worth mentioning are the local variables:

Variable	Value
name	'app_title'
self	<NewsBlogConfigFormAppDataContainer: {'default_published': None}>

So Aldryn NewsBlog may cause the issue, but I’m not sure.

Has anybody have an idea what’s wrong and how I can solve this issue?

[mayankvi-dev]

Hello,

I am also facing same issue and tried to find the solution but no luck.

Please let me know if anyone have solution for above issue.

Thanks

[marksweb]

@NicolaiRidani are you able to move this issue to aldryn_newsblog? The error is coming out of that app, not the CMS itself.
