Hi @didate,

Please run the analytics tables export first, and then I’m sure you tried to clear the cache but could you double check using a different/new browser/profile? If you don’t see the issue in the new/different browser/profile then it’s 100% cache issue. If you still see the issue then we need more info.

I know you said the Network tab doesn’t show errors but what about the Catalina.out log? Please share it without the sensitive info if there are any WARN or ERROR then it might help for sure.

Also, would you please test by creating a new dashboard and adding only this item? Do you still see this issue? Maybe while on the new dashboard with this item, open the network tab and refresh the page, would you check the request and response for this item in the Network tab?

Thank you!

BTW, what is the version of the DHIS2 instance that you are using?

Hello @Gassim

Thank you for your reponse.

I’ve cleaned the cache, tried with others browser, but I don’t know what really happen, sometime it’s working, sometimes it isn’t. Also there no error in the catalina.out.

I’m using DHIS2 version 2.34

@didate

sometime it’s working, sometimes it isn’t.

Maybe it’s a cache issue. Whenever it’s not working please immediately check if the issue persists in a clean/new/different browser/profile/guest mode (which you’ve not visited the instance in before) if the issue is gone then it’s 100% a cache issue.

If it’s not a cache issue then the only way to figure out is by testing. Try to make notes on how to reproduce this issue. Additionally, if you have a test instance that you could give access to maybe this will help as well.

Thanks!

Hi @abdulmajid

Which version of dhis 2 are you using ? 2.34 ?

[Gassim (AL-Gassim Sharaf Addin)]

Welcome to the community @abdulmajid!

Yes, please as @didate asked, which dhis2 version is the instance you’re using?

Please try to clear the cache using Browser Cache Cleaner app as well as from the Administration app → Maintenance → select “Clear application cache” and “Reload apps”

Before you open the dashboard you might also want to try the following options:

@Gassim

Then this is a cache issue still. There are several things to do when cache won’t clear easily:

1. Normally we run the Browser Cache Cleaner app but we might also need to run the Data Administration app → Maintenance → Clear application cache and the Reload apps options.
2. Using Hard Reload and Empty Cache:

@kpvandivier

You can hard reload by using Cmd-Shift-R on Mac or Ctrl-Shift-R on other operating systems, or right-clicking on the reload button while the browser developer tools are open, which is how I got this screenshot:

3. Clear cache and storage from ‘Application’ in the
   Browser Developer Tools, see screenshot:

If you still check this issue in a new/different browser/profile (or guest mode) and still see the issue then please check the Network tab (DevTools F12 → Network tab) if there are any errors and share here, thanks!

@Gassim may be it’s a bug on the 2.34.x versions ?
