Option Name Manager page displaying incorrectly

That worked ...

Thank You for reporting back the issues were caused by mod_pagespeed. It's good to see your hosting provider allows you to modify the configuration settings using a .htaccess file

On the topic of mod_pagespeed, I understand why some hosting providers are installing and enabling this module by default. However, I'd estimate about 98% of the optimizations done by mod_pagespeed can be done by a competent Web Developer / Server Administrator without the need to rely upon the module to automatically "optimize" the site content "on the fly". In some cases the "optimizations" done by mod_pagespeed can be overzealous or actually cause problems.

Don't get me wrong, I'd not saying mod_pagespeed is bad... Just saying you will want to be aware of how it impacts your website... And take the time to learn how the module "optimizes" the site content... And then configure mod_pagespeed to better fit your websites needs (or possibly lack of needs if the site is already optimized)...
