I feel like the australian-charts website is a little bit broken at the moment. I can't access any songs that are currently charting (for review purposes) or can't access the homepage without it coming up with a 403 Forbidden error. Anyone who is accessing it getting a 403 Forbidden error?
No one who reads the forum has the power to fix anything. I'm pretty sure only Steffen can, and it's anyone's guess if he'll ever have time for it. (I believe he was told about it when it started. I did memo him once myself about the broken chart run bar images on song pages as that should be an easy fix, but didn't get a reply. I eventually 'fixed' that one for myself with a browser extension.)
I'm not sure anyone changed a setting - these things (along with the chart run bars, the lack of lines between posts, and the chat room breaking) started in January last year when the site was 'attacked' (no idea in what way).
In case you've forgotten, the 'forbidden' errors can be averted by posting via hitparade instead (change 'australian-charts.com' to 'hitparade.ch' in the URL). I'm not sure about the 'too large' errors if those are still happening though.
I know the answer to that Lizzo issue. If you look at this week's chart https://australian-charts.com/weekchart.asp?year=2020&date=20200126&cat=s you can compare to the previous week and see that every song (besides the new entries) has gained 2 on the previous week. I suspect every single song on that week's chart has been counted twice, hence Lizzo getting 41 extra points since she was #10.
It's an amusing by-product of this that since many debuts are marked as re-entries due to weird database errors and start on 0 WI, you have cases like Purple Hat whose WI is correct, only because these two errors cancel each other out
Same Love's re-entry at #4 in 2017 also didn't get counted in its points.
It gets worse because for 2 weeks in June 2019, the charts were added incorrectly, and though they were later fixed, the peaks weren't and I don't think the points were either. So EARFQUAKE's run is correctly shown as 11-9-11-13-18-23-39, but it still lists an #8 peak from those incorrect charts, and I can't figure out how you'd come to 254 points from that either way. Meanwhile, James Arthur's Falling Like The Stars was in actuality #51 and #65 on those weeks (and never made the top 50), but was put at #49 on both incorrect charts, and now if you search it, you'll see a supposed #49 peak, and if you try to click on it, you'll get a 403 Forbidden.
Also Good News debuted on that 26/01/2020 chart and charted 43-27-42, and the only way I can see to produce the claimed 42 points from that is if 26/1 was not counted at all for it, and 9/2 was double-counted
