Publishing Botflow Popup not allowing Ok to be selected

Background: I am trialling Foxtrot in order to compare with the software my company currently uses for RPA, and in order to do so I wish to try out running processes through Foxhub. I am currently running version 15.1.1.

So I previously posted about having trouble publishing botflows as there was no publish button in my foxtrot version - that is now solved, updating to 15.1.1 fixed that issue.

However, now when I click the publish link and the popup appears, when I click the OK button nothing happens. The cancel and X buttons still work, its just the ok button that isn't working. I have tried leaving it for 10 minutes after clicking the OK button, incase there was a delay, but still nothing.

I have also tried with a different file, and after restarting my machine, all with no result.

I would appreciate help with this.

Thanks, Caitlin
