Hi,

I have my site hosted on a shared hosting

I tried to change theme doing the following way

Prepared a "perso" theme on a local site
Once the theme was ready
I put it into the theme directory on the remote server.
I changed the name of the theme in mysite/_config/config.yml
and the file was changed to the following.

Name: mysite
After: 'framework/*','cms/*'
---
# YAML configuration for SilverStripe
# See http://doc.silverstripe.org/framework/en/topics/configuration
# Caution: Indentation through two spaces, not tabs
SSViewer:
  theme: 'perso'

Then I visited zoraldia.com/?flush=1

The adress in the browser's adress bar turned to this

www.zoraldia.com/?flush=1&flushtoken=31bec36a058a8194b2058ca414d71016

And I get the following message

in a blue bar

[Warning] is_readable() [function.is-readable]: open_basedir restriction in effect. File(/usr/share/php/Zend/Translate/Adapter/I18nRailsYamlAdapter.php) is not within the allowed path(s): (/htdocs:/var/www/zoraldia.com/htdocs:/var/www/zoraldia.com/tmp:/var/www/zoraldia.com/exec_dir:/var/www/zoraldia.com/php-session:/var/lib/lws/:/usr/base/var/lib/lws:/htdocs:/tmp:/exec_dir:/php-session:/usr/share/php)

then

If I just remove the leading www. I can see my site without the message but the theme remains alway the initial one (simple).

I don't see what to do in order to change my theme.

Thank you for help.

try remove entry from mysite/_config/config.yml.
Change theme using admin->setting

Hi Thomas, thank you.

Before reading your mail I tried my theme just renaming it simple.

But now, after, putting things in their original state, It works from the backend settings (I can change the theme). I have just a warning appearing

Warning: Invalid argument supplied for foreach() in /htdocs/framework/core/manifest/ConfigManifest.php on line 655

but the renderring is ok.

Hello Jaaf

make sure to remove 'theme' entry from mysite/_config/config.yml.

I hope it works

I did it

YAML is whitespace sensitive. So 'theme' needs to be indented 2 spaces. You may have done this already. I tried to demo it using a code block here but it seemed to stripe the whitespace.

Also, when setting config via YAML you need to make sure to flush for it to take effect.

@Tim Snadden: Thanks for the white-space YAML sensitivity info. This was driving me round in circles for hours, when I came across this. The tutorials don't warn you of this!
