Dear Paul,
thank you for your detailed information.
I did all your recommandation (1-3). There was no change in behaivor.
But.... if I switch off the "Production Mode" it is working perfect.
So I was reading more about the "Purge CSS option". There is one sentence which gives more details.
- But, this may cause a delay in reflecting your latest page customizations on the live site - because the cached CSS file may still be in use.
This was exact the behaivor of my system. After a delay of minutes the page was correct.
So could you give me a recommendation how to use this mode in an optimal way?
May be it is the best solution to do the development without active Production Mode and switch this mode on later.
Best Regards
