USB disk configuration folders tree missing

[triglia118]

Dear friends, I run into a strange issue... I've used for ages Merlin's firmware 376.45 without any problem. I use an usb hdd NTFS attached to the router, shared with samba and everything was ok up to yesterday.
Yesterday I had to detach it to connect a different hdd for a temporary work. After, I reverted to the old configuration, but the tree folder on the configuration page of the router (samba share) was missing and I cannot add or remove any folder. Buttons to add folder are grayed out. Disk is mounted and connected properly, no errors on main page. I tried a lot of things: changed disk with a usb key, formatted it to ext3, connected to different port, power supplied it externally... no way.
I tried also to upgrade the firmware to the last one (378.53), complete reset and complete format of usb disk in NTFS, but the problem is still there: disk correctly mounted but no directory tree in configuration page and grayed out buttons. It is the same even if I connect a different disk or usb key with different cables, I'm running out of ideas, any help? thank you

UPDATE: after more testing, I found out that the problem is the browser! using Firefox or Chrome or IE on my Win 7 system I have this problem, if I use Firefox (same version) on my old Win XP netbook the configuration page works perfectly. I guess it's something related to addon components (ActiveX, or Java or Flash player or something like that...) ideas?

OK, after more testing I'm sure it's a Javascript related problem. I'd like to know what version of Java do you need to make RT-N66U configuration pages working. Maybe I've updated Java on my Win 7 PC and removed older versions and now the latest Java version has some problem with samba sharing configuration.
Enabling debugger on Firefox I can see an endless loop of requests like this one:

...

but the tree structure doesn't appear in the configuration page. I tried also to re-install Java completely but without success: on other web pages Javascripts are working.
Thank you for any answer.

Java has absolutely nothing to do with Javascript.

Do you have any special characters in your directory names? If so, try renaming them to use only alphanumerics and a dash.

Also, if you are using a USB hub on the port, try disconnecting it and attaching the drive directly to the router usb port.

Dear friends, thanks all for your answers. Finally I found out what was wrong. It was my anti-virus program (Avira Pro) that decided not to allow Java script in configuration page of the router. No idea why and no warning also. No errors in the logs. But, adding an exception in anti virus configuration for router ip, everything works. Sorry for have taken some of your time. This strange issue hasn't ever happened to me.
