same problem
for google login: Authorization Error
Error 400: redirect_uri_mismatch

You can't sign in to this app because it doesn't comply with Google's OAuth 2.0 policy.

If you're the app developer, register the redirect URI in the Google Cloud Console.

for fb login: URL Blocked
This redirect failed because the redirect URI is not whitelisted in the app’s Client OAuth Settings. Make sure Client and Web OAuth Login are on and add all your app domains as Valid OAuth Redirect URIs.



anyone had a chance to solved?

p.s. supports of those two monopilst its not helpfull and not reachable

Both related to incorrect configuration of apps.

which apps do u mean? and how to fix it?

Both, you should follow their support channels.
Error details are directly in those error messages.

man i spent month for this problem and did all steps what was possible.. its still same and support of fb and google not reachable (its well knows issue)

I do not think so, because those errors are pretty common. I recommend to use google/fb support channels as this error comes from their services

plz if anyone faced this issue and fixed it, let us know.. thanks in advance

Wrong settings is al there is... For fb it's easy Google is more complicated to get it to work but it works if you fill all details and especially redirect url  https://yourdomain.com/ggl/1  and second https://yourdomain.com/index.php?page=custom&route=ggl-redirect&gglLogin=1

https://yourdomain.com/ggl/1  and second https://yourdomain.com/index.php?page=custom&route=ggl-redirect&gglLogin=1
where from u got it those links?

@sellbuyrent me

If you read the instructions under your plugin settings there you will find those links normally....

Go to the Google API Console..
Select an existing project from the projects list, or click NEW PROJECT to create a new project:
Enter the Project Name.
Under the Project Name, you will see the Google API console automatically creates a project ID. Optionally you can change this project ID by the Edit link. But project ID must be unique worldwide.
Click on the CREATE button and the project will be created in some seconds.
In the left side navigation panel, select Credentials under the APIs & Services section.
Select the OAuth consent screen tab, specify the consent screen settings.
In Application name field, enter the name of your Application.
In Support email field, choose an email address for user support.
In the Authorized domains, specify the domains which will be allowed to authenticate using OAuth.
Click the Save button.
Select the Credentials tab, click the Create credentials drop-down and select OAuth client ID.
In the Application type section, select Web application.
In the Authorized redirect URIs field, enter the following redirect URLs: https://yoursite.com/ggl/1 https://yoursite/index.php?page=custom&route=ggl-redirect&gglLogin=1
Click the Create button.
A dialog box will appear with OAuth client details, note the Client ID and Client secret. This Client ID and Client secret allow you to access the Google APIs.

I coundt find in plugin instructions  for fb url any links ..for google just one and it's not working with me

https://plugins2.abprofitrade.eu/oc-admin/index.php?page=plugins&action=renderplugin&file=facebook_login/admin/configure.php

Initial setup
1. Create your facebook application on https://developers.facebook.com/quickstarts/?platform=web.
2. Go to Settings > Basic > App Domains and enter there domain of your application
3. Go to Products > Facebook Login > Settings > Valid OAuth Redirect URIs and enter following link: https://plugins2.abprofitrade.eu/fblauth-1/
4. In top right corner switch status of your app to live

the problem with these: https://yoursite.com/ggl/1 https://yoursite/index.php?page=custom&route=ggl-redirect&gglLogin=1

is that if you using language codes on your osclass config, you need to include those too

@Kalosex
