Missing channel icons after update to 3.0.5972.0

[inzombyac 69]

After the latest update to 3.0.5972.0 all of my channel icons are missing. I did a guide refresh and I see several reports like the ones below.  I validated that the url used in the get command does return an image in the browser.  Seems like there is a server side issue.  I can provide a complete log if it helps.

Update: This is still an issue.  I have attached the server log.  It seems like there are other users having the same problem:

I tried manually applying the logos last month, but they were cleared somehow.  As long as the manual logos stay, I may go with that route

The issue is limited to when you change the hidden config switch ImageSavingConvention to Legacy. I have not had a chance to look into that. Try changing it back to Compatible

Was that ever a setting in the GUI?  I've never changed any hidden config files so I am not sure how that was set.  I changed it and restarted.  I had to wait a long time for a library scan to complete and then I refreshed the guide.  It had no effect.  I then manually deleted the guide image that was broken and tried a guide refresh again.  It worked after the deletion.  I went through the rest of the channels and delete those (painfully) but now everything works.  Hope this helps anyone else with this issue.

it was never in the gui.
