Solution: It is estimated that the cache is updated. restart the php service.

Problem 2: The PW system crashes.

How to use so much memory...

Solution: change memory_limit = 128 M in php. ini to memory_limit = 256 M to solve the problem. if any program causes this problem, please wait for a while!
