Recently i learned that file list tag for file manager is creating problem. When we upload a file then it take 12 / 24 hour to show the file. This is a such problem.
I know a great way to solve this such problem.Simply add this tag into your F.M file list code.
tu=:time-beg:YmdHisYmdHisYmdHis:time-end:
Example:
:filelist:d=1 2 3,o=tu,l=10,nc=1,[b]tu=:time-beg:YmdHisYmdHisYmdHis:time-end:[/b],s=:geti-site(1):::
Now You can see your file list is not creating problem.
