Welcome, we have problem with new v3.2.0.
When someone Reseller customer wan't update their configuration settings we got a problem with current portbase.

No matter what settings are changed or not, but when click SAVE we got that problem.

Please look at screenshot from our customer and fix it ASAP.

Thank you for the bug report. This issue has been fixed, so please update your Centova Cast installation again

Thank You!
