This post is just a report.
I saw we have a new update in recent.
And some of datalist happened to some unknown error.
It is mainly about the filter of datalist. All of them worked well before update.
For the first case, there should be hundreds of records but showed only 3 records when it was error.
The second case, “response error, pls contact admin” appeared and no records showed.
All of them were fixed after I deleted the filter, saved , and remade them in the same condition.
