pageinfo.json: ItemNotFoundException
When we tried to visit pages in AEM this morning, any of them could not show up, however they had been working fine till yesterday and we hadn't made any changes since then. When we check the error log, there is a 600MB text file in which there repeatedly wrote "/lib/foundation/core/pageinfo.json: ItemNotFoundException" while we can not find the file "pageinfo.json" anywhere in AEM, Therefore I have to come here for help, I would be very thankful if anyone could tell me how to solve this problem...
