asteeman on "HTTP_Accept_Language does not parse"

Hello,

When I wanted to have HTML coding in the description of the Gallery, I figured I should activate HTTP_Accept_Language. However, if I do that, and save the new setting, I get a message that the option Allow Tags could not be parsed.

I had just rerun Setup (to update MySQL settings), and everything seemed okay then.

Can you advise me on how I can correct this?

Thanks in advance
