Here is the link: https://www.facebook.com/groups/1948226822099948/permalink/2011289432460353/.

And what's the content? For me it says 'You must log in to continue.'

Okay @zhuyifei1999, I have edited task description and added link content.

We are aware there is a problem with uploading to Commons.

What exactly is the problem? There are still people uploading AFAICT. Any steps to reproduce the problem?

Problem was reported by MANY people across Africa so it is unlikely to be a connectivity issue.
I am in South Africa myself at the moment; I face the problem myself. I can not upload images using the WLA wizard whilst I can perfectly upload images using the generic upload system on Commons.

The WLA wizard is here : https://commons.wikimedia.org/w/index.php?title=Special:UploadWizard&campaign=wlafrica&description=&descriptionlang=en

I select the image. I click on continue. It leads me to the next step which is the "Release Rights".

The upload system gets stuck at the Release Rights step. Clicking on the "Next" button does not make any difference.

The expected results is that clicking on the "next" button would lead us to the next screen/step of the process which is "description".

This completely reproducible (meaning... it never works. It is not a random issue happening or not happening. It just does NOT happen). I can only check it from South Africa though.

I changed the preferences languages (I tested French and English) and it makes no difference.

The contest in itself is now closed.
But some UserGroups could not upload the images they collected as part of the contest. Means hundreds of images. They can upload using the regular upload system (which I recommended they do), but there is a high risk related to wrong tagging (which would mean hours of volunteer work fixing tagging afterwards). So yeah... if it can be fixed :----> better

Removing "Move Files to Commons" tag since this is (maybe not the best label) for a new extension that is not yet on production.

I thought I've seen this reported before but could only find old T95599: When using UploadWizard, clicking the "Next" button on the "Describe" page has no effect.

@Anthere, @D3r1ck01: If you can still reproduce this problem:

When this happens, does anything appear in your browser's JavaScript console when loading the page? Sometimes JavaScript errors are a reason for problems. For more information please see:

• Firefox
• Internet Explorer
• Google Chrome
• Apple Safari

Could you try to run the upload wizard with the debug option enabled? Just add debug=true as a URL parameter, like going to https://commons.wikimedia.org/w/index.php?title=Special:UploadWizard&campaign=wlafrica&description=&descriptionlang=en&debug=true

As this has happened to several people, any patterns about the web browsers being used by the affected people?

Any ideas, @MarkTraceur or @matthiasmullie ?

Patch is up.
It affects campaigns where only 1 kind of license (own work) can be selected (which is probably most/all of them).
Not sure how many of those are currently running; we may want to deploy this as soon as possible, rather than waiting for deployment train.

@matthiasmullie, thanks for working on this. Also @Aklapper, wasn't around for a while but I think @Anthere already gave some hints on how and where the problem occurs. Thanks to @matthiasmullie for acting this fast :).

Let's deploy as soon as we can. I'm okay with expediting through the regular process for this one, as long as code review is good.

@Ramsey-WMF, you are up, could this be deployed so our WLA participants finish up with their uploads? @Anthere, do they still have some time or time is over?

We'll do our best to get it out as soon as possible.

Thank you very much @Ramsey-WMF. We'll be waiting.

The fix is now deployed - can someone check that it's working now, please?

My preliminary test shows the Next button at the release rights step is working now. We could use more people testing it to make sure everything is okay.

Thanks @Ramsey-WMF and @MarkTraceur, let me update the participants on Facebook and let them test and give feedback. Thanks very much.

A few feedback from participants of the contest say it's working now. That all is well. Waiting for more feedback but I think all is well now. Thanks very much everyone :)

Awesome ! Thanks to all of you for your quick help ! Most appreciated !

Can we now mark this as resolved? Or is there anything else to be done?
