ALL VIDEO SHARE

I just installed allvideoshare and cannot access any administrative functions other than the main dashboard menu. If I attempt to select anything from the dashboard I get a blank screen with this message on top:
500 - An error has occurred.
JHtml: :jquery not supported. File not found.

Return to Control Panel

The Chrome inspection console shows this error:
westmichiganflorafauna.org/administrator...view=videos&task=add Failed to load resource: the server responded with a status of 500 (Internal Server Error)

I have this version installed - All Video Share - 3.1.0 FREE Version
on this version of Joomla - Joomla 2.5.28

I was having a similar problem with a previous video player "Spider Video Player" but it has just been completely uninstalled with the same errors. I have tried disabling several other plugins and modules but always get the same error and problem. Hoping you can help, thanks in advance, Gary.

Sorry, All Video Share 3.1.0 version works only with Joomla! 3.x versions and don't work with Joomla! 2.5 versions.
