ut joomstagram error - Error validating access token

Hello.
You need to generate a new token (regenerate it within the app) and paste that token into the module's configuration. If you have multiple modules on the same site, you need to add the new token to all of them. Then, access your site via FTP and delete the mod_ut_instagram folder. Finally, refresh the frontend where the module is displayed.
Regards

Have you updated to the latest module version?
Have you verified that your GDPR is working correctly? On some sites, instead of the domain extension (.com, .net, etc.), it says gdprlock

If you're sure you've configured everything correctly, then I don't know what the problem is. The message you see on the screen is a response from the Facebook API; the module is just displaying it. If it says the key is invalid, it's because an invalid key is being sent, which could be for these reasons:

1. The key is indeed invalid.
2. You didn't paste the complete key into the module's configuration (there can be several in one place; paste it into all of them).
3. The key wasn't cleared from the cache, so the expired key is still being sent.
4. Although I doubt it, perhaps a cache extension stored the expired key and is still sending it in the request.

Currently, over 20,000 active sites use our module, and none have reported this type of problem.

Three days ago, we released a new version of our GoodNews template, which is why we also released a new version of the module. If you have consistent traffic, the module doesn't need to generate a key every 60 days; the keys are automatically regenerated.

Since we develop locally, no one visits the templates, so the key for GoodNews expired. We cleared the cache and updated the tester key for Instagram and Facebook, and we also used that same key in our online demo, which you can see here: demo.unitemplates.com/goodnews/index.php/lifestyle . Therefore, it's working normally both locally and remotely.

You mentioned that you had a response with role issues. That's why I'm telling you, the Facebook Instagram Basic API is like a house: you need a key to enter, and if you try to enter the wrong key, it will send you a message according to the key's status. Currently, it says your key is invalid, and that's because it's invalid.

I assume you're obtaining the key following the module's documentation, right? Because there's another way to get the key, which is through the Facebook API, and this key won't work in our module because they're different APIs.

I don't think we can say anything more about this, because the message isn't a module error or problem, but a message directly from Facebook's servers. You say your keys are correct, Facebook's response says they're not, so we can't guess whether it's right or wrong.

Regards.
