Plugin deactivated automatically due to error

Hi,

I updated wp and the Envira plugin deactivated and disappeared, it is no longer listed on the plugins list. The message is now gone as well. I tried to install it and it fails because the files are already there. The gallery is gone from the site and what you see is the gallery id

I have been searching for a couple of hours and am not finding anything.
I deactivated and reactivated all of the plugins, cleared my cache, checked the live preview in seventeen, didn’t try actually changing the theme yet.
??

Thanks
Suzanne
