Hi Demis,
Thank you VERY much for your support! I will look into all of that today…
Yes, all my servers use the latest Version
I was playing around with all those settings, mainly on the LINUX side. I will increase it. I like to avoid, that users get errors just because the backend is performing stuff, that the end user cannot understand…
For the rest of you answer, I will give you feedback as soon as I have some results.
