Upgrade from 2.5.x to 2.6.0

[mmcshane]

I upgraded my install of phpMyFAQ to the latest version 2.6.0. Everything went fine but now some of my previous faq's now have this text before the actual faq data:

phpMyFAQ notice [8]: Undefined property: PMF_Helper_Category::$treeTab in Category.php on line 146

phpMyFAQ notice [8]: Undefined index: in Category.php on line 146

phpMyFAQ warning [2]: Cannot modify header information - headers already sent by (output started at /home/mjmcs2/public_html/techpointpro/faq/inc/functions.php:173) in index.php on line 574

It's not all of them just a few. I tried updating the record (changing the font) and saved it but the result was the same.
What am I doing wrong?
Here is the website:

Note: the first faq listed has the text before the data:
http://techpointpro.com/faq/index.php?a ... artlang=en

Thanks in advance,
Mike

Hi Mike,

we already fixed a lot of issues in 2.6.0, on viewtopic.php?f=3&t=10240 you'll find most of the fixes.

Upgrading to 2.6.1 did the trick. Thanks!
