Something went wrong with the plugin API.

Hello,

I’m trying to install the demo data of the theme I bought (https://themeforest.net/item/your-journey-travel-blog-wordpress-theme/11477970).

However, some plugins are required to install. I installed all of the required pluging, except one, the Flickr Instagram Picasa Gallery plugin. It’s gives the error message ‘ Something went wrong with the plugin API.’ What should I do to make it work?

Thanks in Advance!
