Recently we have had problems in assisgning our pupils to a site - or sharing permissions. Usually we copy the emails of pupil sets to assign them to a site - however now we have to enter a symbol to verify the action - the problem is we can't see the symbol because it comes up with a red cross (the image/symbol can't be displayed/viewed). Does anyone know what the problem is and how to get the symbol to display? Right clicking/Show image does not work. Any ideas?
