Hi,
First I apologize if I made a new topic. I dont know what to search as I do not know what to search and I dont know the specific name for my problem.

Anyway, my problem is my homepage is alright. But when I click a menu my page looked like this


And when I click one article it show page error that says:

Please help me. I dont know what to do. I uninstalled kunena but still same problem occuring.
Again sorry if I made new topic about this.
Any help would be greatly appreciated.

G'day, greatnuvi, and welcome to Kunena. I'm sorry to hear that you are having problems.

It's a little difficult to see what these problems are from the picture you posted. It's also hard for us to help if you do not have Kunena installed.

When you have installed Kunena, would you like to provide us with your K 1.6 configuration report . We will try to help you with your problem. Thank you.

Thanks for the reply sozzled. I reinstalled kunena again. Comparing to the first installation process that I made before, the number of files that showed up during this second installation are lesser. I'm just mentioning this for possible info. Anyway, here is the config report: :ohmy:

CONFIG REPORT DELETED!! AFter 2 hours from first edit.

Edit: First edit
I read this and found out that the mootool is disabled. I thought from the beginning that it was already enabled since its with joomla installation. I enabled it but stll the same problem.
Any idea what i should do next. Thanks

Second edit: 2 hrs after first edit
Problem solved!!!
I had set the global config of my joomla to Search engine friendly URLs to "Yes" before and I change it to "NO" and everything come back!!!
I have no idea what happened but it was solved through changing Yes to No in SEF URLs in joomla global config. Its unexpected solution for me.

Please read Search Engine Optimization (SEO) in the Wiki. Pay close attention to all the steps and you should not have problems with SEF URLs. If you were using a third-party SEF product then you may encounter different problems. We recommend that the use of certain third-party SEF products should only be attempted by experienced users and, generally-speaking, third-party SEF products tend to cause a lot of difficulties with Kunena. Some third-party SEF products actually cause Kunena to stop functioning altogether!

Yes, you can enable Joomla SEO and you will not encounter those "404 - Component not found" errors. You just have to make sure that you enable Joomla SEO correctly.

Also very good post by Matias is in there (even it's only in K 1.6 Installation and Upgrade place): Before you install Kunena 1.6 - check list

I tried to follow the guide (not up to the .htaccess guide) but no success. still making errors.
