Cannot save reports or pin items to the dashboard

[mikemunn]

Our organisation is a new user for Power BI and I have been testing it's suitability and all was going swimmingly until today when the follow issues appeared:

1. When trying to pin an item to a workspace dashboard I get the following error, strange thing is the element I'm trying to pin is one that i have successfully pinned previously (a bar chart in this case)

Sorry, can't pin this visulization yet. Please try again later.

We're working on this feature. Please send us any other feeback about Power BI.

2. If i try to edit a report on the web interface and try to save it down, it also errors, this time the message is as follows:

Something went wrong

Unable to save the report
Please try again later or contact support. If you contact support, please provide these details.

If you need more information just let me know.

OK, so I fixed the issue since posting this.

I had applied a custom theme to the reports, removing that and setting to the default fixed all the errors...
