Twitter login showing error

First, please verify what version API access your Twitter account is enabled for? Version 1.1 accounts have been suspended due to v1.1 API being deprecated. This is the top reason why an existing app would stop working and throw that error. (I coincidentally deleted our 1.1 standalone app while looking at this and am having trouble creating a free v2 app for our project... ugh)

Please verify that the callback URL for your application is correct. It should be in the form "www.yourdomain.com/index.php"

Next, please verify the App ID and Secret Key and that they match what's in the JFBConnect > Provider > Twitter area. I'd suggest regenerating the secret key and copying from the app again.

Another older setting "Enable Callback Locking" in the Twitter app needed to be enabled. I'm not sure if this option is available any more.

Let us know the results of above and we'll go from there.

Actually hold off on trying those. I was able to create a new app and am having the same problems. A code change will be needed. Working on it now and I'll get back to you.

I have quite a few changes made for both the Twitter provider plugin and the core OAuth2 code in JFBConnect. I have some cleanup to do, but am able to successfully log in on a new v2 app with the Free developer access. There were quite a few deviations that Twitter made from the standard base OAuth2 implementation that were causing issues.

When I have it ready do you want a) me to send you a test build, b) you send me FTP credentials in a Contact Us form or c) wait for a release to go up that's more tested? This is pretty raw right now and may have some bugs.

I was testing my fixes some more and encountered some bugs, specifically with the channels feature blowing up. Plus we only have an app with the Free API access so I keep getting locked out of making requests while debugging, making progress a little slower. I think I should be able to get a test build out tonight or early tomorrow morning.

Sorry for the delay. We were having trouble with our build server that had to get resolved first. I've added you both to a Beta Test group. If you go into your My Account > My Subscriptions, there should be a 9.0.255 beta build available.

There's still some wonkiness to our build server, so I couldn't do a build for just this release (i.e. there's other changes in this build as well). If you'd like to unzip to a different directory and copy over the following files, these are the ones used for this bug fix:

Twitter Plugin (You can find these files in packages/plugins/jfbconnect/provider_twitter.zip)
plugins/jfbconnect/provider_twitter/profile/twitter.php
plugins/jfbconnect/provider_twitter/provider/twitter.php
plugins/jfbconnect/provider_twitter/provider/twitter/config/config.xml
plugins/jfbconnect/provider_twitter/provider/twitter/channel/stream_outbound.xml
plugins/jfbconnect/provider_twitter/provider/twitter/channel/stream.php
plugins/jfbconnect/provider_twitter/translations/en-GB.plg_jfbconnect_provider_twitter.ini

JFBConnect core (You can find these files in frontend directory)
component/frontend/libraries/authentication/oauth2.php
component/frontend/libraries/authentication/oauth2base.php

I highly recommend backing up your site and the original files before you copy over. This is not fully tested. Also to note, we only have Free Access, so I can authenticate with Twitter and I can post to Twitter in channels. We do not currently have the ability to test Twitter stream data coming back to channels right now.

I'm in the midst of changing JFBConnect for Joomla 5 support and Bootstrap 5.3.2. It's possible I broke something with the translations when I sent that. I'll have to get it a little more stable before I share another build.
