Slideshow stopped working after upgrade

Hi!,

I am working on a project with a Joomla website that hasn't been updated for a long time.
I just bought the Pro version of Slideshow CK.

After the update, I went and opened all of the slideshows and clicked on the link to update them.
I also downgraded one time, but that made the entire website broken and gave a notification template not found.

Unfortunalty I cant get it working and I need a solution ASAP.

Could u please take a look at my website?

I will message u in a private message the administrator details.
EDIT: It seems I cant send a private message on this forum.

Hi
I'm checking your home page, and there are 2 JS errors in your page. This breaks the slideshow script
you must check that and fix the JS errors in your pages, then let me know
CEd

PS : try to disable the plugin
/plugins/content/mgthumbnails

problem solved, it was also with the plugin JU sticky panel, once disabled, everything works
