wipertraining

I am experiencing the same issue with a fatal error after updating elementor 3.56 and betterdoc on wipertraining.com that required me to rename the betterdoc folder to gain access to the admin and the front end. Also getting error `The authenticity of elementor.3.6.4.zip could not be verified as no signature was found.
Unpacking the update…
Installing the latest version…
Removing the old version of the plugin…
Plugin update failed.`
