Not sure if this is a bug or not but when I try to upgrade my marina it just takes me to the hideout page without starting the upgrade

You are missing one of the resources. It should red out the exact missing resource. I am checking now to see if this is a general error or if this never happened anyway.

None of the resources are indicated as missing. I have the required numbers and more

Just a thought, Are any of the resources set to sale to players on the market?

Probably you do not have the required space then. You will need to upgrade the mansion. You can check the available space there.

For example:
Details:Available fields: 120
Occupied: 120
Empty Fields: 0

I am still investigating this. It does seem to be an issue preventing the display of error message, affecting private marinas only. I will post again once it is fixed.

Fixed.

Like I said above, it was an issue blocking the error message for Private Marina upgrades.

Thank you PK
