[TYPO3-workspace] Changes in workspace not shown in preview

[Nils Hodyas]

Hi there,

I shall fix the following problem:

After editing in draft-workspace, the changes aren't there in the preview. 

It's TYPO3 4.7.19 with Templavoila.

I'm told that everything worked just fine until recently (an update maybe).

The system seems to be buggily implemented, updating the extensions didn't work, and at one point I saw an extension php code popping up in BE. So the problem could come from there.

But maybe someone of you has got an idea. 

Thanks in advance.
