The update of the plugin is not good.
Restart the transfer and make sure everything went as expected (with FileZila, there is a tab with errors during transfer).
"PLUGIN ERROR: "./plugins/LocalFilesEditor/admin.php" is not a valid file".
>_< I have uploaded the plugins directly from the piwigo's zip (Extracted). Why is this showing this to me?
BTW: I have upgraded just now from phpwebgallery 1.7.0
