Server Write Access Issue on WordPress 5.6

Hello there,

I have attempted to use the H5P plugin with WordPress 5.6; however, when attempting to "Add New" H5P content I am getting the following error message 'A problem with the server write access was detected. Please make sure that your server can write to your data folder.' I've checked with my hosting provider: Fasthosts, but there doesn't seem to be any permissions issues with writing to the data folder. 

Can somebody please advise me on how I should proceed?

Thanks
