Alfresco shows only blank page.

[statira]

Guys, urgent help required!
Some users see only blank page accessing alfresco, profile recreation helps for some time (not long), share.log says:

2016-05-25 08:58:20,824 ERROR [org.alfresco.web.site] [http-apr-80-exec-3] javax.servlet.ServletException:
Could not resolve view with name 'site/ditanalyst/' in servlet with name 'Spring Surf Dispatcher Servlet'

and

And why it says 'site/ditanalyst/', not 'site/ditanalyst/dashboard'? What does it mean?

All users are members of this site ditanalyst, so am I, but I never encounteed this error.
How can I fix this view? What might be the cause?

There are also errors in alfresco.log:

[douglascrp]

There seems to be more hidden errors in the log file.
Please, if you can, post the full log file somewhere and share the link here.
It will be easier to help you by looking everything since the service startup.

[statira]

Thanks for reply,
here are the log files:
https://drive.google.com/open?id=0B1eEHJ1Ks_teanIydmJVemNRdzA - alfresco.log
https://drive.google.com/open?id=0B1eEHJ1Ks_tedFZVYndqbWFOUnc - share.log

Hello? Guys, I'm getting desperate here.(( Does anyone has a clue what's happening? I've changed nothing in my config before this problem appeared. I have upgraded to a newest version since. The problem migrated to a new installation.

[douglascrp]

Don't you have a backup from a moment before the system stop working?

You have lots of different kinds of errors happening. Authentication, conversion, IOException: File name too long,

Do you know what happened before that state? Any unusual behaviour or usage?

Any try to execute a batch update? Any new customization deployed?

You said you have upgraded it. You should not do that for a broken system.
The right thing to do in this case would be to solve the problems, and only after that, try to upgrade.

I recommend to you to revert that, by restoring a backup, and then try to fix everything before trying the upgrade again.

Now, if you don't have a backup in place, it will be hard.

[statira]

Well, I don't think I have a backup that old and anyway it's kind of late to revert to a working state, too many changes were done since this problem appeared and it would be sad to lost them.

As I said nothing changed in the system that could cause this error, no customizations, no addons, nothing changed in config files. So it seems it came out of nowhere.
I upgraded to see if the problem would migrate to a new installation. Since I believe the problem is not in configuration, because it used to work for about a year without this error, could anything be wrong with the postgres database or a file system (alf_data)? If one of them is damaged could it cause such a malfunction? Why 99% of affected users are from one site?

I know there are lots of errors in logs, I just don't get which of them are relevant to this misbehaviour.
For example what an error Could not resolve view with name 'site/ditanalyst/' is about? I've seen errors about dashboard "Could not resolve view with name 'site/ditanalyst/dashboard' or 'user/guest/dashboard' ", but what this one is supposed to mean? It appeares for different sites, one of them is the affected one, but others work fine so it's not the issue? What does Probably a stale user Session mean? Didn't find anything about this one.
