I had exactly the same problem. On 2.6.0 + starlight I had shadows; Updated to 2.7.2 and lost them. Like you the 'Lighting and Shadows' boxes were ticked but greyed out What had happened is that 'Hardware skinning' had been disabled. This *must* be enabled to allow shadows 2.7.2 performance seems better with shadows compared with previous versions
