I use Atahualpa 3.4.4 and WP 2.8.5.
With an older version of Atahualpa the sidebars appers without problem.
In the options I think all is correct:

what is the url?

The url was:

http://test.lacuinavermella.com

Thank you!

what page doesn't the sidebar show on?
What version of Atahualpa?
Are you using any plugins that create pages?

This pages don't show:
http://test.lacuinavermella.com/qui-som/
http://test.lacuinavermella.com/products-page/

The version of Atahualpa was 3.4.4 and I user wp-e-commerce what have created some pages in the WP...

Thank you!

if you disable the wp-e-commerce plugin do the sidebars show up?

I can't disable the plugin there was a lot of work and data on it...

This page not contain any info of the plugin:
http://test.lacuinavermella.com/qui-som/

Thank you!

disabling the plugin should not lose you any ofthe data or settings. They should be stored in the wordpress database. To be safe, do a backup of your database first, that way you can restore it if there is a problem.

I disabled de plugin and the problem persists...

How can I do?

Thank you!

please list all teh options you have at ATO->Style & configure SIDEBARS

Here you have screenshots of all the options:

Ok they look fine which means that there is something else you have added to the site that is causing this situation.

What other plugins are you using besides th eecommerce?

Try disabline ALL the plugins and see it the problem persists. If it goes away, add the plugins back one by one till you find out which one is doing it

I have disabled all the plugins and have the same problem!!

I can create an admin user for you if would you like to see in action...

Thank you!

send me a PM with the admin user and PW

I need to set some debug displays. Can you set the Atahualpa/functions folder and it's contents to a permission level of 755 - make not of the current permission lever so you can change it back later.

I changed permission from 777 to 755.

Thank you

something didn't work - set the permission of bfa_get_options.php to 777

Permission set...

you have all sorts of extra code in the Atahualpa theme folders like sidebar.php and sidebar2.php
What are these things???
I suggest you delete everything in the Atahuapla folder and load a fresh copy, some how you have added in code that is wrecking havoc with how the theme works. This is why sidebars are not showing up.

well looks like getting rid of all the extra php modules added to the atahualpa theme folder did the trick
