Hi-
I have had to reregister my site every time I want to run a scan. Once I reregister it, I have to refresh the page in order to be able to get the update and do a scan. However, when I do this, the registration once again disappears. I donated in February (I know, that was a while ago). Is there a reason why my registration does not show up in the plugin?
This sounds like a caching issue. If you clear your cache and refresh the page it should show that you are already registered, or given enough time the cache may expire and this page would then show the correct registration status.
Please let me know if you are still having any issues with this and I can help you troubleshoot further.
