Missing MIME-Objects (BEx Web Analyzer)

Hello @ all,

a few days ago we changed the portal desktop for SAP NetWeaver Portal (7.4 SP11) to the "Ajax-Standardmodus Portal-Desktop", changed the LAFservice to "LESS" and implemented a new design.

The problem we got now is that everytime we want to use the BEx Web Analyzer a warning appears which says:

Can anyone help me out?

Regards,

Nicola
