I don’t really understand what has gone wrong here all my controllers  
etc are in place correctly but I get this error message in my log:

Parameters: {“action”=\>“view”, “id”=\>“home.html”, “controller”=\>“page”}  
Rendering layoutfalseactionhome within layouts/front  
Rendering page/home  
Completed in 0.11562 (8 reqs/sec) | Rendering: 0.08692 (75%) | DB:  
0.00388 (3%) | 200 OK [[http://www.en.scottisharchitecture.com/home.html](http://www.en.scottisharchitecture.com/home.html)]

And the pages will not display.

The site works fine on my winxp machine but not on the Linux server.

Any help would be appreciated.

Actually, I’m seeing a similar symptom over the past few days -  
rendering blank pages, with no errors in the log (200 OK) - I’m  
currently attributing it to exceptions being trapped somewhere in the  
internals. I’ve seen it happen with bugs in my helpers + with with  
usage of the url helpers. Occasionally (don’t know the conditions)  
I’ll see a normal exception - so it’s not a generic exception/logging  
problem.

In my case, log\_level is set to :debug. I’m running on trunk (r6157)

Debugging is a bit tricky now.

Actually, that’s not an error message at all. That message says  
everything  
went OK. The app did exactly what you told it to do and didn’t  
encounter  
any problems. Without more info re: what you told it to do, it’s hard  
to  
offer concrete advice.

Check for hard-coded paths in your code. '' vs ‘/’ will cause  
problems,  
but they usually get flagged with ‘file not found’ errors. CSS errors  
don’t  
though.

I don’t know if it’s related, but I’ve run across pages not showing.  
Here’s  
what happened:

I updated code for the new from block syntax:

\<% form\_tag("/posts") do %\>  
…  
\<% end %\>

Even though our intention was to upgrade to 1.2.2, I didn’t realize they  
had  
the project frozen at rails 1.1.6 (vendor/rails) which doesn’t know this  
syntax, so we got blank pages. We removed the vendor/rails dir so it  
would  
use the 1.2.2 install and everything was fine.

The only other time I got a blank page was with Internet Explorer and it  
was  
due to an html error on my part.

I hope this is of some use…

It sounds to me like there’s something wrong with some setting, maybe in  
Rails and maybe in some other component, underneath the application  
itself.  
When I have a problem like this, which I do all too often ;-), I work  
hard  
to cut the app back to the bare bones in an effort to get a repeatable  
problem that’s one step away from a non-problem.

You mentioned having a subdomain set up. First thing I’d do is try to  
get  
the basics of what you’re doing, which is selecting the view to find  
from  
the database and then rendering it, working with no subdomain involved.  
Then take the step that introduces the subdomain and see if that is, in  
fact, where the problem shows itself.

Once you’re there, if you haven’t ‘seen the light’ yourself, I’d  
recommend  
reposting with your new detail to the rails-deploy list. The same folks  
are  
here, but the signal-to-noise ratio for this type of problem is much  
lower  
over there.

Sorry I can’t be more help.

Best regards,  
Bill

Bill,

Hi thanks for your response.

What I am telling it to do is, I have a view controller setup:

# this is the main view controller

def view  
simple\_name = Page.clean\_input(params[:id])  
@page = Page.find\_by\_simple\_name(simple\_name)  
if @page.template.size \> 0  
render :action =\> @page.template, :layout =\> ‘layouts/front’  
else  
render(:layout =\> “layouts/front”)  
end  
end

Which looks for the .html extension, searches my database for the  
template and then display the page using the layouts/front.

It seems to be finding all the view/pages because if I remove or rename  
any of them I get an error message(template couldnot be found). It is  
just not displaying anything in the browser.

In firefox I get the 500 error from the .htacces file and explorer I get  
a page cannot be displayed.

I have set up a sub domain to access the /public directory and got rid  
of any redirects but I still seem to be getting the same message:

[http://www.public.scottisharchitecture.com/home.html](http://www.public.scottisharchitecture.com/home.html)

My hosting comapny have upgraded to ruby-1.8.5 and rubygems-0.9.0, this  
is where the problems started. They are telling everthing is working  
fine their end.

I am very confused, does this information help at all?

Angela.
