Xojo Web site DB Error

On OS X 10.8.5 with Chrome version 30.0.1599.69:

When I follow this URL:

https://www.xojo.com/support/webinar.php

The Xojo website reports this error:

Fatal error: Database error: “ERROR: current transaction is aborted, commands ignored until end of transaction block” (0) SQL: SELECT nextval(‘error_log_id_seq’); in /home/website/xojo/www/source/lib.database.php on line 738

If I login with my account on xojo.com and then visit the URL again, it’s all good, no error.

It does not occur in Safari.

Thanks, we’ll look into it.

I have the same problem with any page on the Xojo site where login is required, also with Safari.
Just a reload of the page will then give me the correct page.
