@scott, @devstorm,
Thank you for all your suggestion for the solution.
I understand that MySQL max_allowed_packet limit is changeable,
so I will try setting it as high as possible.
If not possible, then I might have to set the file mode as an alternative.
Scanning checksum data should be another good idea, but to do that, I have to revise the program so that checksum data can be inserted in DB table, and that will take a lot of time if I assign it to every website I own.
(But if the future wpfmp will have that feature, then I want to try it!)
Thank you for your response, Scott.
I see. But why doesn’t this problem happen when file save mode is set?
(Even with the file save mode, the plugin still needs to check a lot of files.)
Is it related with the database timeout? And if so, isn’t it possible to fix the plugin so that the search finishes before the timeout?
