Can you include your site's backend and FTP access once at http://stackideas.com/dashboard/site so we can better have a check?

I've updated the OP info to include requested information.

It seems like you provided us that login credentials no longer work, this is what i hitting now :

JFolder::create: Could not create folder.Path: /home/public_html

Username and password do not match or you do not have an account yet.

Issued should be resolved. Please try again using the same credentials.

Thanks, i can able to login from your site backend now.

But it seems like this user account doesn't have Superadmin privileges to access installer page, you can check my screenshot here : http://take.ms/S23DD Please advise.

Changed. Should have all privileges now

Thanks, I can able to access now.

It seems like you hitting this following error once uploaded the Komento installer.

Warning

JFolder::create: Could not create folder.Path: /home/public_html

Warning: Failed to move file: /tmp/phpvfX6vG to /xxx/tmp/com_komento_launcher_pro_3.1.2_joomla_113477 (1).zip

The reason why you hitting this error is because these following directory folder doesn't set to writable permission, you can check my attached screenshot below.
/home/public_html/administrator/logs (Log folder)
/home/public_html/tmp (Temp folder)

Can you request with your webhosting provider to help you update this 2 directory folder permission to writable?
Once set to writable permission, you should able to install Komento into your site.

Got in contact with my hosting provider. I had just transferred my hosting services and migrated my site. What happened is that the directory paths were incorrect. They fixed that and then I tried installing Komento again. That fixed it. Thanks for your help.

You're most welcome. Glad to heard your issue resolved.

Just for your information, I have locked and marked this thread as resolved to avoid confusions in the future. Please start a new thread if you have any other issue in the future so it will be easier for us to manage your inquiries.
