After Login into the admin panel, I have this screen, I am not sure how to fix this.
I have just moved from one hosting to other and added one Extension.
I am not able to see the extension so, wasn't available for remove the extension.
Use SSH or FTP to access your app/etc/modules
directory and open the XML file of the last installed extension.
Search for the tag <active>true</active>
and change it to <active>false</active>
. Save the file.
Also clear your /var/cache/
directory. Flush Redis and Vagrant if any of this is installed.
