Foursquare OAuth suddenly not working - foursquare

I have a Foursquare app that I'm trying to get integrated into a website I'm working on, it has been working fine up to this point but suddenly trying to go the URL "https://foursquare.com/oauth2/authenticate?client_id=[MY_APP_ID]&response_type=code&redirect_uri=[REDIRECT_URL]" is giving me an "invalid_token" error, which is strange to me because I haven't even gotten to the second part of the OAuth "dance". Am I missing something obvious? Thanks!

We're able to reproduce and are investigating. Thanks for the report!

There is something wrong with https://foursquare.com/oauth2/authenticate endpoint. Try https://foursquare.com/oauth2/authorize instead.

We just tweeted to #FoursquareAPI and #4sqSupport. Its broken for us as well as IFTTT

Imgur API (rapidAPI) no longer works

Two days ago, something changed and the RapidAPI endpoint of the Imgur API just stopped working for uploads.
Also, it seems Imgur isn't responding over at the RapidAPI discussions, so hopefully their engineers see this. There's a thread about it here. I have no idea why Imgur does not have a contact point for their paying customers though.
My website has worked just fine and let me upload stuff with no problems, but it just returns a 404 error on the https://imgur-apiv3.p.rapidapi.com/3/image endpoint now. No other errors or messages.
Seems like many developers are getting this error. This can fix the issue
Add the ?client_id=<imgur_client_id> query string parameter to API endpoint ​(POST /3/image).
However, you can always write to RapidAPI support team at support#rapidapi.ciom

passport-facebook node app doesn't seen to work

https://www.facebook.com/dialog/oauth?response_type=code&redirect_uri=https%3A%2F%2Fpanorart-victor3991.c9users.io%2Fauth%2Ffacebook%2Fcallback&scope=emails&client_id=547453695448009
My app is still under development.
It used to work with facebook login. But it suddenly got to the 500 error with the text:
Sorry, something went wrong.
We're working on getting this fixed as soon as we can.
I thought this might be the facebook internal network error but the issue had been on for almost a month.
Does anyone have some idea why it's happening?
I'm also using google oauth with similar logic and it's working fine.
For me it was the scope passed via passport that was incorrect. I used the google scope which was profile and email, whereas facebook required publish_actions. Hope this helps

403 error on Lighthouse3D's web

I am really pissed about the fact, that Lighthouse tutorial web (http://www.lighthouse3d.com/) is throwing me 403error forbidden. Don't you know what they are doing, or will it be in the future online? I helluva need it to my school.
It might be that they do something on their side , or if site requires some kind of auth , they didn't provided solution nor explanataion. Tried to load it , same happens. Might be that Apache server and mods has to be restarted or fixed. I got many times 403 error , like when I try to open www.openlicenser.org which also throws this error , and it wasn't fixed yet , I think.
As Rudolf said, the website is experiencing problems on server side.
But, if you want to check something urgently here is a useful link:

Foursquare Explore API endpoint seems to be broken

I have been using Foursquare Explore API endpoint since I have started developing an application. But recently it seems to be broken. It keeps on giving me following response
warning: {
text: "There aren't a lot of results near you. Try something more general, reset your filters, or expand the search area."
}
I am trying to get the response from the following HTTP URL -
https://api.foursquare.com/v2/venues/explore?ll=40.7,-74&v=20121124
(adding my credentials to the above URL)
the issue has been noticed couple days ago on this page
Foursquare venues/explore returning empty data set
I'd really like foursquare to keep us informed, because we can't rely on their API if no information about what's going on is provided :(
This bug has been fixed, all queries should be working now. Thanks for bringing this issue to our attention.

What does it means &sa=U&ei?

I have a website, today looking at the log, I found some request to a page from my server with appended this variable &sa=U&ei.
Could you tell me guys what &sa=U&e could mean? Could be an attempt to find Nullable Scrips? Could be a security threat?
&sa=U&ei=XuRBT92UFseYhQf_w7HeBQ&ved=0CNYBEBYwYw&sig2=Rt1Cr_FCPD1-6VYu__Oavg&usg=AFQjCNFlHVaDQL--kgDbOn2vNgUqwUOsTA
The error in my log is:
A potentially dangerous Request.Path value was detected from the client (&)

But nevermind. I found the offending culprit. Seems that for some
reason my "GoogleEnhancer" became "incompatible" with Firefox. It
worked fine even before I updated to 10, but go figure. And it wasn't
the whole add-on, it was the "Use Google Classic" radio button turned
on. I got this add-on after Google started making their search engine
so... oh, what's the word I'm looking for... umm... oh, yeah...
crappy!

I figured out what it is... I have an add-on called google enhancer
which obviously hasn't been updated properly of late. Disabled it and
it worked fine. Well that was a waste of a thread. Thanks for the help
though guys.
So, the unnecessary part of the request is created by an outdated add-on for Firefox, nothing serious. The visitors with that add-on have more problems than your website :)
Practically, it could just be simple url request.
And the random texts you are seeing could be an autogenerated random string to maintain sessions. As there seems nothing wrong with the URL, and those sa and ei simply means, that these get variables are assigned some values, which would then be used in your application, for may be session management or other purpose.
From the face of it, it doesn't appears to be any hackable stuff.
