for some time I have the issue that cornerstone needs a very long time to load (over one minute!).
The problem appears on all my sites. Even on new and blank WP installations with only X-Theme installed.
My sites are hostet on Hosteurope and Strato.
It seems that the script "cornerstone-endpoint" causes the problem. It takes a very long time until it loads.
I have read some topics in this forum. Some other X-users seems to have the same problem.
There you said that the problem is caused by the hoster. I have contacted the hoster (hosteurope) and they say on their side it is everything good. They say the issue is caused by the script.
I hope you can help me and the other people with the same issue!
Thank you very much!
