I have the recent donations block workig on all my sites.
There is a problem with the security. When someone makes a donation, it goes through paypal.
Your site needs to receive the IPN (comformation of payment) from paypal.
When it comes from paypal, your site bans paypals IP because it sets of the DDos pretection security.
Therefore who receive no IPN and no record of donation reaches your sites database.
Nobody came up with a proper fix, but I was able to get it to work.
Steps:
Go to ACP>User Admin>Ban Control - you should see a banned ip which is the paypal ip. Delete it and clear the banlists.
Next go to ACP>Security>Special - Set 'DDoS Protection Level:' to LOW - Save it.
Now when you do a donation, you will receive the IPN log and donations will appear in the recent donations block.
Be patient, it can take a bit of time for it to appear, but it will come.
You can see on our site:
http://www.aaquacks.com that we have it working.
NOTE: I don't know how vulnerable having DDoS set to low will be on your site. Someone wiser can update us on that.
Maybe Helter can put the instructions somewhere as a tutorial or something for others to use as a fix.
