Hi,

Thanks for the clear description of the issue (I hope all issues description would be as clear ).

Can you check if you have javascipt erro rin the browser console ?

NB : on this free forum, we only support "laste stable version", so possibly you could migrate to V11.4.3 (or V11.4.4)

Hello,

I have updated to V11.4.3Console Log is given error information specialy with selection of Philippe Timesheet, as attached.

Regards.

Sébastien

Issue is written in the console
 

This means that connection was shut down during reception of answer.
This may be done by server or by any network device.
It can be a PHP or Apache configuration that stops the response (max input time, max execution time, max input vars, ...)
It can be a proxy that finds unexpecting sting in the response or too long response.

Try and open network tab in browser console.
Play erroneous case.
Select line pointing to refreshImputationLine.php, check for headers and response. Possibly you can get some information here.
Otherwise, you'll have to check logs of all network items between server and client : 
 - PHP / Apache
 - Proxy
 - Firewall
 - Router
 - ...
 

Hello,

No log errors everywhere I looked for (Apache, PHP).
Here attache console tab info.

Regards.

Hello,
All var have been doubled : max_input_time =120, max_execution_time = 240, max_input_vars = 24000
But same issue to display imputations.
Sébastien

Need to see the Network tab of Dev Tools : Headers and Response
Example
 

Hello,
Since restart of the server, which was not responding, Timesheet access for Philippe is now reachable.
I will keep an ey on it and will copy the requested panel status if the case appears again.
Thank you.
Sébastien

I have the exact same problem, time sheet not displaying for one user.
In the browser console, dojo.js reports NS_ERROR_NET_INTERRUPT.
Apache timeout is set to 300 sec.
php.ini max_execution_time is set to 0.

Can't see anything in apache nor projeqtor logs....

Most often this issues are generated on Clienbt Side (what explains that it does not work only for some users)

Current issues are :
 - conflict with a browser extension : try another browser or remove/disable all extensions
 - blocked by security item : disable anti-virus ans firewall (just the time to test), avoid proxy or VPN

Thanks.
The cause was a WAF (Web Application Firewal) causing a timeout while inspecting the response. The problem was happening for this specific user because he has a lot of assignments, thus analysing the response was more time consuming.
We deactivated this step in Coraza WAF.
