Hi everyone,

I am have trouble updatimg the DNN_Bog module settings
When I go to "manage" blog and select the bog I want to change the setting for eg. user permissions then click update I get a screen with "The service is unavailable".

I have tried different skins including the new skin that comes with ver 10.1.0 10.1.1 10.1.2 and used different browsers and different computers.

This error shows up into admin logs.
Any ideads any suggestions welcome.

Thank you in advance.
Trevor

If you can make it happen from scratch and it is not something specific to this instance, I would report an issue at https://github.com/DNNCommunity/DNN.Blog/issues

If you find out that it is site specific than you need to try and create a test page, see if multiple modules don't play nice together, etc until you can find the combination that makes this happen.
