I'm using one instance of 7.2.8, now running about 50 small websites successfully, building up over the last two years.
Suddenly, yesterday, when a user or the administrator logged into the back office, the icons in the black column on the left (Media, settings, users, members, etc) didn't display. The same problem occured with different users, computers and browsers.
If the user refreshed the page, however, the icons display. But on logging out and logging back in, the icons didn't display until the page was refreshed.
Your help with this problem would be much appreciated.
Here's the sequence of events with the log records.

Nope. there is nothing there that I can see, which might be causing your issue. They're just general logging messages. Nothing out of the ordinary..
What version of Umbraco is the site running?
You could look at upgrading, if feasible, but suppose it's not the end of the world as long as the CMS is still functioning and like you said the icons do come back eventually!
I would suggest, bringing a copy of the site down to your local machine and then perform a test upgrade there. That way if anything goes wrong, you won't have affected the live site and you can just delete those files and try again.
I would also suggest going from 7.2.8 to 7.3.0 and the working up each major version until you are at the latest version.
Craig is right, your best bet is to pull the sites local and do local upgrades of each major version.
I've had issues in the past upgrading from 7.2.8 to 7.3.* if you don't the 7.3 step so make sure to do that.
Also, Umbraco don't advise running lots of sites from a single instance, it can be risky. It could be worth taking this opportunity to break them down into more manageable chunks.
You could look to split your sites up into say 5 instances of 10. At least this would then reduce the potential for all sites going down. Just something to consider :-)
Honestly, I'm not 100% sure.
All I know is that it is recommended. I'm guessing there are security considerations as well, such as all the sites using the same database to store site information in. Size of the sites could impact each other and bad site coding could result in site data getting muddled.
I guess it just adds another level of consideration into it. For small information based sites, I don't see it as a huge issue but just thought I would flag that :-)
The thought of upgrading a single instance that could kill 50 sites would terrify me and if I could reduce down the number of sites that could be affected I would want to do that.
Hopefully someone from Core, or who knows a bit more why the best practice isn't to do that, can add more info for you.

Thanking you in anticipation.

Hi Roger,
Are there any console errors in the browser when this occurs?
Also, is this specific issue to a certain browser OR is it happening on all?
Regards
Craig
It occurs on several different browsers and computers and no console errors.
Hmm, that is strange!
Can you check the Umbraco Log file to see if there is anything useful in there?

Does this give any clues?

I'm running 7.2.8. I'm petrified of upgrading so I keep putting it off. I have about 50 sites running off this one instance of Umbraco.
Any advice on a safe way of upgrading? And should I go the whole hog to the latest version?
Hi Roger,
I bet you are! Feel your pain man...
I would suggest, bringing a copy of the site down to your local machine and then perform a test upgrade there. That way if anything goes wrong, you won't have affected the live site and you can just delete those files and try again.
I would also suggest going from 7.2.8 to 7.3.0 and the working up each major version until you are at the latest version.
See the following guide before proceeding: Version specific upgrades
Thanks for all your help today, Craig. It help to know you're sharing my pain.
With this new found Dutch courage....
Roger
No problem! :)

Thanks, Nik.
Is the risk of running lots of sites on a single instance only the fact that one problem could affect all sites or are there other risks?
