Thanks to James for checking things out and resetting the forum. I was tied up all day Sunday and Monday with family commitments and was delighted that James found some time to get things checked out and back up and running so quickly.
This morning, I found that we were behind on one of the security updates for the forum software. However, it was warning that it may not apply correctly; I applied the update anyway. It claimed to be successful and the forum looks like it is still working properly. Please let James or me know if something seems to be awry.
After applying the security update, I found an additional setting to further deter hackers. I turned that on.
Hopefully, between these two changes, and the new password, we won't be visited by a hacker again.
Thanks for your patience during the outage.
