Hi,
I am sorry but this error message doesn't say anything. It is not PHP error message but It is a browser's messages.
Are you seeing this error message AS SOON AS you install the publish the ZoomEffect plugin?
Any why are you getting back to the backup?
- Can't you access your joomla backend after installing ZoomEffect plugin?
- Can't you simple unpublished the ZoomEffect plugin through Joomla Plugin Manager?
Also; zoomEffect plugin has been updated last week and we added Virtuemart 3.x support to it. I am not use if you have the latest version but you are sure you are installing the "for Virtuemart 2.x" version, right?
Because our ZoomEffect has 2 versions
- for Virtuemart 2.x (works with V2.6.x + J2.5)
- for Virtuemart 3.x (works with VM3.0 + J3.3)
Regards.
