Open Microscopy Environment

Hello,
we have just upgraded our local Omero server to version 4.3.3 and experiencing the following issue with the updated Webclient. After logging in, at the "Home" screen, all images are displayed as usual. However, when selecting an image, the directory structure is displayed on the left side but neither the image nor further details about it are displayed on the right-hand side, i.e. on the right-hand side there's only a blank panel.
Using the client software, images and annotation are displayed correctly. Moreover, it does not appear to be a browser issue because the problem does not exist when using the Webclient of the demo server.
I cannot rule out that the issue was already present with version 4.3.2, as I did not test the webclient back then, but I'm sure that it worked with 4.3.0. My first guess is that some files have not been updated/copied correctly when upgrading the local installation.
Any ideas/insight about what might be the source of the problem? Do you require any further information from my side to locate the problem?
Thanks very much in advance,
Joern

Could you try running bin/omero web syncmedia and then re-loading the page? This step was temporarily missing from the 4.3.3 upgrade instructions.

Sorry for any confusion.

Hi Josh,
thank you for the reply. However, I followed the recent upgrade instructions which already included that step. To be on the safe side, I ran the command again. No change, though, and the problem persists. Any further suggestions or checks that I could run?
Thanks very much in advance,

Hmmm...the only other thing I can think of is that the path has changed to your installation directory and your Apache configuration (or similar) didn't get updated? We've seen this ourselves recently.

What frontend (apache/nginx/none) are you using and how is it configured?

Cheers,

Hi Joern,

Referring to Josh's message, could you please check if you have access to http://YOUR_HOST:PORT/appmedia/omeroweb/images/nuvola_script-run16.png
If not, it means you need to update your web server configuration file (Apache and nginx configuration):

Code: Select all

Alias /appmedia /Users/omero/Desktop/omero/lib/python/omeroweb/media


Otherwise, if you could see that PNG please make sure you restarted webserver once you upgraded the omero server. Stopping omero server does not call bin/omero web stop.

Once this is clean, please clean your web browser cache.

Thanks Ola

Hi Ola and Josh,
thank you very much for your suggestions. Both an update of the nginx configuration (indeed forgot to update that one) and clearing the browser cache solved the problem. Maybe adding a reminder about these two steps to the upgrade instructions would be useful for other administrators, too.
Thanks for your help,
Joern

Hi Joern,

you're very right. Thanks.
