An expert on Easyexperts(https://easyengine.io/easyexperts/archive/) deployed our multisite of wordpress.
Since there is no reply from him for more than 40 days, so I need other guys to take this work.
After check errors log:
I found there are lots errors, some issue are related to server configuration, but some others related to plugins.
For now, I would like divide this debug work into two parts, one is for server configuration, and the other part is debug applications or plugins.
The easy engine official guys would be prior to do this work.
