Cannot load page tree or template list

[quickjeff]

Hi Guys, 

I have been debugging a site for the last 2 hours and cannot solve the issue. 

I have a site running on 3.0.148. 

I installed the Kongondo Blog module and was updating the templates to include the website style. 

Once everything was set and done, I checked the page tree to see an error appear. 

Template must be assigned a name before 'filename' can be accessed

The same error appears in templates. 

Debugging Steps

• I checked the templates in the server to ensure I didnt accidentally delete the namespace. 
• Deleted cache in browser and server under assets

Still no go. 

Any help is appreciated. 

Thanks!

I had the same issue.

The problem was that there was a templates record in the database created with no-name. When I deleted this record (with Adminer), everything was working again.
