Windows: Undefined index: vjs_sync in C:\piwigo\plugins\piwigo-videojs\admin\admin_sync.php on line 78

Due to an human error I have to setup my piwigo (2.9.5 with 55k pictures/videos and 550 albums) from scratch :-(.
So far so good, all pictures and video are online. Have installed my normal plugins, i.e. videojs, but I do get the following errors when trying to generate new thumbnails.

Notice: Undefined index: vjs_sync in C:\piwigo\plugins\piwigo-videojs\admin\admin_sync.php on line 78
Warning: array_merge(): Argument #1 is not an array in C:\piwigo\plugins\piwigo-videojs\admin\admin_sync.php on line 78
"You ask me to do nothing, are you sure?"

mediainfo, ffprobe, exiftool and ffpmpeg are in the path (c:\piwigo) and the videojs shows me 4 green arrows.

Piwigo 2.9.5
Operating system: WINNT
PHP: 7.0.5 (Show info) [2019-05-02 00:39:57]
MySQL: 5.5.5-10.3.12-MariaDB [2019-05-01 23:39:57]
Graphics Library: External ImageMagick 6.9.3-8

Have already tried to deactivate, delete and re-install the plugin with no success.
Table piwigo_image_videojs does exists.

I have seen, that there were several issues with 2.9b. Is there any chance to download the 2.8b version.

Have found in a backup an old version 2.8b. This version is running like a charm.

Please also see #148 - can this be fixed for the latest version?
