Hi...love the theme. Thank you. But I'm getting the following when I search for terms (tags/words in the title) associated with 1 of the 3 test posts:

Catchable fatal error: Object of class WP_Error could not be converted to string in /home1/unlocki3/public_html/continuumscience/wp-content/themes/atahualpa/functions/bfa_postinfo.php on line 271

I'm using WP version 3.0.1 and the latest version of Atahualpa, which I think is 3.6.7. I'm using a search widget in sidebar, but it also happens when I use search that already comes with Atahualpa. Would someone please help me...I appreciate it. Thanks.

First I suggest you update your WP install to 3.1.3
second do you have all BUGFIX's for your version applied? (they can be found in the 'New Version & Updates' forum and sub forum)
--if not, apply them before we go any further and re-test

Thank you for responding. 1. I was afraid of upgrading WP because when I did, the plugins I use to organize info didn't work anymore; but, I'll try again. 2. I don't know what bugfix I'm looking for. Do you have a direct link to what is needed to solve this specific problem? Thank you.

Is there any way to fix this problem without upgrading WP to 3.1.3. Plugins I use to structure content are said to NOT be compatible with WP 3.1.3. Are there any bugfixes that will deal with this specific problem...I'm assuming the problem is with bfa_postinfo.php, since this file is mentioned in the error message. Thank you.

Look in the 'new version & updates' forum for the threads starting with 'BUGFIX 367-........' and apply them all and we will go from there.

Yes, I have applied them all, but there is no change. As far as I can tell, when I change the permalink structure to only use post id, the problem seems to go away. But I don't want to just use the post id in permalink; I'd like to also use the post title.
