Not working with Oxygen Builder

Hi There,

Your plugin doesn’t work on my back-end with Oxygen Builder.

Everything is updated, not many plugins around, I did clean my Cache,…, still nothing.

I get an error, in a red box at the top corner on the left side, telling me:
“Failed to process the clipboard contents
Error: Invalid clipboard contents”

Do you know if I did something wrong, or is it only cause of updates?

Thank you,
Regards,
Eric
