Something is wrong with my wordpress backend

Hi,

Last night I was working on a site, I am not sure if I did something wrong while working with FTP or something, but suddenly my Bloom email opt-in plugin stopped working and the whole site sort of acted funny, menus were rearranged etc.

So I shut everything down and reopened it this morning, the menus on the website were more or less back to where I left off but my Bloom opt-in form< was still not working.

I went to the Bloom plugin to check my opt-in forms and though they were still there in the backend, the interface was all messed up, with menus from my website showing on the top of the plugin backend! So I thought I’d update the plugin, but when I tired, this is what showed up in a pop-up, along with the same menu items from my website on the top of the pop-up!
“An unexpected error occurred. Something may be wrong with www.ads-software.com or this server’s configuration. If you continue to have problems, please try the support forums.”

Additionally, on the WordPress Dashboard there is now additional space on top and if I try to update any plugin the menus form my website start showing up on top of the pop -up.

The theme I am using is Genesis Sample Child Theme. I am working with Chromium browser on Mac OS.
Some Plugins I am using are:
Bloom
CSS Hero
Elementor
Genesis Dambuster
Genesis Simple Edits
MyStickyMenu

Could any of these be causing problems? I am not sure how to progress from here, please help!
