System users can not have duplicate names. System users can not have duplicate names. Use another name - facebook

I'm having a problem with the Facebook setup with Shopify, I have an error sentence that says:
"System users can not have duplicate names.
System users can not have duplicate names. Use another name."
I have tried everything but the problem persists!
Who knows how to solve this problem please?
enter image description here
I have contacted Facebook support several times, but each time they tell me to do something but it never solved the problem.

CAS 5.3 login screen modification with extra field

I am working on apereo CAS 5.3.x, and in my application Login operation expects 3 data elements - username, password and a group code.
I need to add group code combo box. this combo box will get data from the database and at the time of submission need to submit the selected data from combo box also.
I have tried the code from this URL https://apereo.github.io/2019/02/25/cas61-custom-login-fields/ also.
but it is not working.
can anyone help me on this issue?
I have tried the code from this URL https://apereo.github.io/2019/02/25/cas61-custom-login-fields/ also. but it is not working.
The reason it may not be working is that the document quite early on states the following:
Our starting position is based on:
CAS 6.1.x
That doesn't seem like it would match your CAS version, which as you state is 5.3.x.
So for that article to work, you need to be on the appropriate CAS version, and then try it out.
PS When you do, avoid phrases such as "it's not working". "It doesn't work" doesn't work. Please clearly state the problem, the issue, attach logs, describe versions, changes made, etc. This post might share a few points on how to troubleshoot and share results.

Determining how many people have been added to a facebook group by a single member

I am the admin of a Facebook group and am trying to keep track of how many people each user has added. I cannot seem to nail down how I can easily write a script to:
Determine how many people a User has added.
Echo that to a file in the format $User:$number_of_added_members.
I've been made aware I cannot do this with the API, I am banging my head against a wall here. If anyone could at least point me in the right direction it would be much appreciated.
I just did this...
actually i am a programmer and did it in the hard way because i needed group by users. I hoped that the graph api at least give me an xml of user with added by in order to make my code read it but it did not so what i did is just to copy the table on the members page and paste it on a txt file and make a python code read it and make a dictionary of user: number_of_users_he_added.
it was quick but there is a problem that the members page does not give u all the results, its infinity scroll and i have a lot of members.
u can write a js script that read the dom instead of copy paste or even a chrome extension but still have the problem with the infinity scroll.
if facebook provide the added by field in their graph it will be great
Maybe you can work with the site which lists all members and look for the string below the member which says "added by on " But I'm not sure, how long this stays before it switches to "in the group since"
Edit
Use a crawler software like the one in Symfony to traverse the HTML of the page. You will need a PHP CLI for this tool. DOMCrawler from Symfony

TYPO3 multiple Domains causing preview error

The following domains are set up:
Now, when I edit a tt_news entry and click the save-and-preview icon, the domain looks like this:
http://www.eyec-inspection.com/http://www.eyec-inspection.com/news-events/ar... etc
The system uses the first domain to open the link, so when I move www.eyec.de to the top, the link changes accordingly.
I've read in a forum that this is supposed to be standard behaviour, but highly doubt that.
Is there anyone experiencing a similar issue or knows a fix for this?
Most likely you entered the protocol into the domain record. You must only enter the domain (without http:// or https://) into the domain record.

Cannot access App Namespace

I created my app's namespace using the wrong FB profile, so I deleted the app. And now I'm trying to recreate the namespace and it won't let me - it says it already exists. It doesn't exist! I deleted it! Help! Another user posted a similar question and got an answer suggesting he pick a different name. I'm hoping you will consider that I can guarantee it doesn't exist because I deleted it. Is it hopeless? This is not a name that can be easily changed with punctuation - this is a trademarked product name. And yes, I own the trademark. Please help! Thanks!
It may be temporarily cached and you can wait a couple of days and it'll free up.
But, the more important point is that the app namespace means very little. Practically the only time a user will see it is in their address bar when they go to your app. Most users will not find your app by directly typing in it's URL, instead they'll discover it through App Center or they'll click on a bookmark on Facebook, on a search result on Facebook or elsewhere, they'll see a link or request in news feed or they'll see an add for it.
App Namespace is used a lot in Open Graph code and such, but none of this is ever exposed to the user, only the developer. Therefore, having to use a difference namespace than your original one will make little difference.
As an example of how little app namespace matters, what do you suppose Farmville's app namespace is? farmville? Nope, it's onthefarm
Once you delete an app you created on FB, you can't re-create it with same namespace. It is a bug in FB. Once I had same issue and when I tried to get hep from FB community help center, I found many people having same issue. But the issue still not solved.

Facebook Developer - Unnamed App

I setup a facebook app for my client's website like I've done many many times before, but now for some reason each of the apps I create have a duplicate app called 'Unnamed App'.
At the moment I can't delete them, and when I try to load the delete URL directly, it just says 'Please try again later.' I used to be able to delete them, perhaps its just a temporary thing, but REGARDLESS, these unnamed apps just keep popping up again and again even after I delete them.
Anyone experienced this before or know what to do to fix it??
This appears to be a bug. I've filed an internal bug report. I'll post when I have an update. Thanks for the report!
