gpsal, please can you let us know what version of Gibbon you are using? If it is v14.0.01, you will see that we are already looking into this issue here, and there is some advice on how you can help us, as we can’t recreate the issue. Thanks!

I’d advice you to update to v14.0.01, as there is an important security fix included in that release. Please can I ask you to look at this issue, and follow the advice given there? That will help us recreate the issue.
