UPDATE:
Added and removed a few faucets to keep everything up to date!

Good chance that this will once again be no help, but just in case -- you can download the version that I used if you go to https://github.com/chipshotDEV/Faucet-Builder/tree/a3b8f3efa477e0e590f45456392b841bfcc2a0f8, and "Download ZIP" from there.

The script is being updated fairly regularly, so it is possible that it will be fixed. I think it has been updated once or twice already since I wrote that tutorial, so I do not know if that might be making a difference.

The site that I created to show it in action is here: http://makebucks.byethost12.com/

Sorry, I do not understand the error. Here is a free host that I know works, though: https://byethost.com/
That is where some of the screenshots in the guide are from.
You could also try http://www.000webhost.com/, but my personal experience with them is that things did not quite ever work how I wanted them to.
Please let us know if you get different results with a free host!

I am sorry, I am really having trouble figuring out what this could be. The admin error appears to have something to do with "admin_message_html", but I don't know what to do with that.

Did you try running it on Byethost, or a similar free host? I am not sure if using ddns could have an effect or not.

Sorry this is not more helpful...

Hi!

I am sorry you are having trouble with this. I will do what I can to help, although I am not sure what could be causing this.

First, is your Xapo app "Redirect URI" set to your site's URL? It looks like it is, but I thought it might be worth double checking. And it might be worth checking to make sure none of your keys have any extra spaces or anything, although I doubt that is it, too.

Did you make any changes to any of the .php files?

I am trying to change my own script / app to see if I can duplicate the message your site gives. I hope that we can get this fixed for you!

Do please let us know how it goes for you!

Xapo faucets hook straight up to your Xapo wallet, so there are fewer fees involved. This is one of the reasons many Xapo faucets pay more.

Oh, thank you so much!

I added your faucet to my list and rotator!  
If you are interested, I also have 2 faucets, 1 FaucetBOX-based and 1 Xapo-based that you could add to your rotator (if you like them, of course).

Thank you everyone for the great feedback! Has anyone tried it out and set up a new Xapo faucet?

I am thinking about writing tutorials for other faucets (FaucetBOX script, etc.). Would there be any interest in that?

My own blog you mean? Yes, it is. I hope that is ok!

Thank you!

I am also very open to suggestions of features to add, such as other information to list, and of course faucets that should be added. 

I have changed the settings, so it will disappear below a certain width. Is it still blocking your page? If so, may I ask about what resolution you have?
Thank you so much for the feedback!

Yes, unfortunately even some of the "good" faucets are like that. I will keep that in mind as I add/remove some in the next few days, so thank you for the feedback!
Were there any specific ones that you remember being particularly difficult?
