Hi, tried to use the Synchronize Local Directories plugin, but it gets stuck in this while statement until PHP execution times out.

             while (strcmp($source_dir, $piwigo_dir) > 0)
            {
                #TODO: there is a dir in piwigo, which doesnt exist in the source. Delete it in piwigo.
                next($piwigo_dirs);
                $piwigo_dir = current($piwigo_dirs);
            }

The inequality in the comparison stays true as soon as $source_dir has a value larger than "/".
My source directory has an extensive tree of directories and sub-directories with photos, but my destination directory, the piwigo galleries directory, is empty.

Any suggestions?
