Task list is suddenly empty ... but tasks are entered!

Anonymous — Mon, 26 Jan 2026 18:19:17 GMT

I thought we did a reload last night, but when we checked the whole task list was suddenly empty ...

Although we did configure all reload tasks (QMC) ...

We did saw this before ... and after changing some tasks (and the QMC saves data a couple of times) the task list appears again ...

But how can this task list become empty suddenly? Did saving go wrong in the QMC??

And more important ... how can we be sure the task list does not disappear again?? Now no reports are reloaded because the QMC / QEMC can't find the list???? In which XML is the tasklist??

Hi,

I have the same problem, could you solve it? I'm using QlikView Server 10 SR1, is this a bug?

Regards!

In 9 SR6 (QEMC Status), if you do not check "Indent dependent tasks", the list of task dissapears. So the solution is to check that option and this way it works fine.

Hi there,

This certainly sounds like a bug. References to reload schedules are in a number of files. One of the main ones is WorkOrder.xml. There are a list of other related files (v9 - but I believe these have not changed) in this forum posting:

With QV 10 SR 2 out in the next day or so it may be worth taking a look at that when it is availble.

Regards,
Steve

I had the same problem where my task list was suddenly empty.

I applied the publisher license key as this was part of my renewed license agreement and I missed some tabs within the QMC (e.g. the tab to add the reload-error email). Appying the pubisher lic deletes all your tasks and completely changes the way qlikview server works ! Sh..t !

Solution was to completely strip the applied publisher lic (and then restore a previous seting from

C:\ProgramData\QlikTech\ManagementService\QVPR\Backups )

There is no 'normal' way to delete an applied publisher lic .

Also miracously my other problem with disapearing tabs was also solved...

Maybe this extra info helped as I did not read this cause and this solution on any other thread.

Thanks for posting @andries_bos.

What you have reported here seems is the same scenario as explained on:

As you mentioned is very important to have this into account when applying such licenses.

Also some useful information when using the old activation method with Serial and control number.
