How to correct rewrite_module - UNDEFINED?

On my Host tool, everything is fine but the rewrite_module setting.

It shows : rewrite_module - UNDEFINED

The mod_rewrite is both well loaded by the apache conf and working smoothly. However I would like to correct the error and indicate dolphin where to find the module. Does anyone know how this could be achieved?

This is normal if PHP doesn't run as an Apache module - it can't query Apache for its list of modules. If permalinks work, everything is fine and this can be safely ignored.

I see! thank you.
