I am having the same error. Is there a problem with this plugin?
I have tried to use the plugin with and without the addons and received the same result.
I have other issues with the plugin:
-The pager does not work
-The gallery view page is distorted
-The lighbox efect does not align on the page
Thank you. I was able to resolve the issue by renaming the plugins directory and uploading the plugin again.
