The Kunena team has announce the arrival of Kunena 7.0.8 [K 7.0.8] in stable which is now available for download as a native Joomla extension for J! 5.4.x/6.0.x./6.1.x. This version addresses most of the issues that were discovered in K 6.2 / K 6.3 / K 6.4 and issues discovered during the last development stages of K 7.0
This category is only for reporting defects or problems with Kunena 1.6 test versions with Joomla 1.6. This is NOT a support forum - there is no support for test versions. Users should NOT install K 1.6 alpha or beta test versions on websites with live production data.
Question
Forum content highlighted on home button instead of forum
a) make sure your Kunena menu has "kunenamenu" as its unique name
b) make sure this menu contains at least one item with the alias "forum" (mine is a Menu Link that links to a different "Forum" entry in the Main Menu)
c) Create your menu structure in the Main Menu. Make sure the item you want to use as the "Forum" item is an "Entry Page" type.
a) and b) must exist in some form (an item called "forum" in a menu called "kunenamenu"). If they don't, you'll always get the problem you're describing.
By the way, Kunena 1.6.3 does not yet support Joomla 1.6 very well. You're better off waiting for Kunena 1.6.4, which is due out very soon.
