Question Fatal error: Call to undefined function kunenaBuildRoute

Hello

I wake up today and checking my site i get this very strage error all over my site

Fatal error: Call to undefined function kunenaBuildRoute() in /home/ccccccccccc/public_html/includes/router.php on line 311

Yesterday everything was running perfect, nothing as been installed or change since...

Any clues ?

I am running Kunena 1.5.7

Hello,

Please upgrade to k1.5.14 at least, because you are using an outdated kunena version.

Upgrade is just install the 1.5.14 version ?

When i make update i get the following error: XML Parsing Error at 3:84. Error 9: Invalid character

Then on admin i have this message:

La mise à jour de Kunena 1.5.14 a échoué!

Il manque l'ajout de quelques correctifs pour votre forum, et quelques fonctionnalités ne fonctionneront pas bien.
Essayez de faire de nouveau de mise à niveau. Si vous ne pouvez pas mettre à jour Kunena 1.5.14, vous pouvez facilement revenir à la dernière version.

Two days ago I upgraded a website from K 1.5.4 to K 1.6.4 ... yes, it's true! The job took about an hour to prepare the site, upgrade Joomla and a few other extensions to their latest versions, and then it took less than two minutes to go from K 1.5.4 to K 1.6.4 and everything worked perfectly!

After that I spent about 10 minutes adjusting a couple of colours to fit with my site theme and the forum was running smoothly ... and super fast!

Why not try K 1.6.4 on your site? Read K 1.6 Upgrade Guide for more information.
