It would be really helpful if someone can fix my login issue, I started using codoforum today and the FB, Twitter and G+ login are not working.
http://community.worldanimeclub.com/index.php?u=/user/login
As you can see by visiting the above link, when someone clicks on the login buttons an error message "The page you are looking for does not exists! " is shown. Please help me in this.

Also second issue is that I cannot seem to change the default logo, Do tell me which files I can edit to change the logo.

Last but not the least, i would like to integrate my Wordpress user database with this forum, is it possible? Both websites are on same server and domain.

Also where can I add the Recaptcha keys, I can see the recaptchalib file is available, so that means the feature is enabled!
Hope some one can help, Thank you

You can change the logo by replacing the image here:
codoforum/sites/default/assets/img/general/brand.png

Last but not the least, i would like to integrate my Wordpress user database with this forum, is it possible? Both websites are on same server and domain.

Yes, it is certainly possible. The forum that is used here has been integrated with Drupal login system.
Do you have knowledge in creating a wordpress plugin ?
We will be adding documentation for login integrations to Drupal, Wordpress, Joomla, etc soon.

Also where can I add the Recaptcha keys, I can see the recaptchalib file is available, so that means the feature is enabled!

Codoforum does support recaptcha but you will have to enable it manually.
To enable this feature you need to open the table codo_config in the codoforum database.

Then, change 'option_value' of captcha from 'disabled' to 'enabled'
Add you public and private keys to captcha_public_key & captcha_private_key in the table.

I added App ID and secrets of FB, Twitter and Google, sometimes login works, some times they don't. Yes I am a Wordpress developer, but this new forum environment is very different, so it is a little hard for me to get my head around. hope you can help.

We asked that to give you more specific instructions.
If you are not in a hurry, we suggest you to wait for the documentation.

As for the errors, it looks like they are a side effect due to our API changes.
We will fix them in Codoforum V2.4

Have you left the callback URL blank in twitter app ?

If yes, please set it to some random url like : http://google.com
