This will have been about the 3rd system I have upgraded to version 11.x and each with each system I have experienced multiple issues with the web interfaces after upgrading. (I chose upload files during the upgrade as well as manually uploaded all files after the upgrade). It seems like there are missing files (if I attempt to manually upload all system files again I get warnings about files missing). I have compared manager software/primary folder to the SD card primary folder and sometimes certain files are there other times they are not. Ultimately (the system I just upgraded today) I attempt to do web management and Java spins attempting to load but nothing works (upgraded Java, using IE, etc.). I van't even log into self administration, page just stays blank. I thought I would post this out to see if anyone has experienced issues with any of the web interfaces of IP Office after 11.x upgrades!. Thank you in advance for any insight
