Error in event logs - thumbnail generation?

Hi Nick

 

I seem to be getting quite a few errors appearing in my event logs on the server hosting HAP.

 

The error that keeps appearing is:

I have tried browsing to the API page for this but receive the following error:

As far as I can tell - other than not having the icons for images (as it always seems to be a jpg or other image that it is happening on), the only other problem is the amount of entries it keeps putting in the event logs. Do you know how either we can A) Fix it or B) Stop it logging the error?

 

Thanks in advance!

Have you tried the latest HAP+ release? I know I put some fixes into one of the 7.1x relases
