Custom portal themes - anyone seeing issues on recent NetScaler 14.1 builds? If I use the default images these load fine, but any custom images that get uploaded with the theme don't render. They exist in the page code but just don't load... I haven't dug into a packet trace yet to see what's going on at that level.

No problem here. Please check if the source files are still present.

Yes they are definitely present on the filesystem. I've seen this on two separate NetScalers, one is a clean build... time to open a ticket :-\
