Upgrade Issues

• 1.5.X upgrades are not always properly removing old styles, JavaScript and image files
  • Issue Fixed: Well, mostly, as of version 1.5.2 the reset button will remove the old files assuming the permissions are set correctly.
• 1.5.X upgrades are sometimes failing
  • Workaround:Remove the plugin and install a new copy. Use the reset button afterwards to remove old setting and instantiate new ones.

Caveats

Flash (i.e. YouTube videos, etc.) will sit atop the Lightbox Plus display no matter what the z-index is. This is an issue with Flash.

See Flash content displays on top of all DHTML layers at Adobe for details.

To work around this issue you will need to add something like the following to your <param /> and <embed></embed> tags:

        <object><param name="wmode" value="opaque" /><embed wmode="opaque" [all other embed settings, file src etc.]></embed></object>
