I'm running Joomla 1.5.25, with Multisites 1.2.81.

The install went fine, but when I attempt to add a new Template, only a partial page loads, without CSS, etc (image attached). All other menu options appear on screen fine.

Running the RT_modulus template.

Did you tested with other templates ?
Do you have the same problem with other template or is this specific to this RT_modulus template ?
