I hope you are well today and thank you for your question.
It seems you have installed the plugin incorrectly.
Please delete the plugin on your site and reinstall it from Appearance -> Install Plugins as displayed in the attached screenshot.
I am not getting it doing the same thing on my site so would you mind if i log in to your site and do some troubleshooting? If this is ok then could you please share me your site log in details privately by adding them in the box having text “Click here to share private content. Only you and forum moderators will be able see it.”?
At the moment everything is gone…Could it be because I tried to install the plugin again?
No reinstalling plugin doesn’t affect the site. It must be due to any other reason.
Could you also look if I can get my old site back? I don’t know what I did but I lost all my pages and blogs…
If you have taken backup of your site then we can restore it to get your old site back.
