# [Radiant] Re: multi_site extension and 0.6.7

```Hi Keith,

what have you changed to get it running?
I have changed 'clear_cache' to 'clear_model_cache' 2 times in
\vendor\extensions\multi_site\lib\multi_site\page_controller_extensions.rb```
```
Otherwise the server does not start.

- Have you done the same?
- Is this correct?

I still get some errors in the admin control if I want to change "slugs" ...
I couldn´t test it on localhost. Is this possible?

Thanks,
Patxi

I realize that this does not yet work, but I thought I would give it a try. Unfortunately, I am stumped. There were a few errors with the clear_cache method in the page_controller, which I think I got. Now I am getting an error whenever I try to login in... I am pretty sure it is in the application controller, but not really sure what it might be. Anyone else try this. I really like this extension, and have whole "families" of websites based on it
```
The error is:

```
```
wrong number of arguments (1 for 0)
Extracted source (around line #):

Any help appreciated.
