coffeecup: Read the first post, third paragraph ("NOTE: .... ") :-)
D'oh! Serves me well for not reading everything. :P
adaliabooks: Ah, yeah that's my server (well my business server, but I use it for the script). I retrieve tag info for users from there so it probably needs to be unblocked for any of that stuff to work.
I might try and rework that a bit so it's more robust, when I get the time to do any proper script work... Too busy making pizzas at the moment!
Yeah, the uMatrix extension was blocking any XML HttpRequest to your domain. After allowing them, everything's fine. No need to rework it as far as I'm concerned. As I said above, it's my fault for not reading all the available info carefully.
I wonder if that's the reason why it didn't work on eiii's end either...
