Ok, well I haven't used 2.05, mine came with 2.02 loaded. I don't recall having a problem with the logs though. I suppose you could either reload v2.05 or go ahead and update to 2.06. I might try a factory reset and see if you you can view the logs. If you have critical settings on the router, Do a save config to file before factory reset.
Besure to clear the browsers cache too.
Since your seeing this across the board on 2 different PCs and browsers, I presume there could be an issue with the FW. If you have critical settings on the router, Do a save config to file before doing the following:
Factory reset.
Update using the .bin file unpacked from the zip file you get from the Dlink web site.
Factory reset once more.
Can reload the config file at this point or check the logs and see what you see then load the saved config file.
