On one specific server (shared hosting), the update to 3.7.0 caused the panels not to appear (dashboard, all websites and settings). In the JS console there appeared several errors like
Error: "[$compile:tpload] http://errors.angularjs.org/1.6.5/$compile/tpload?p0=plugins%2FCoreHome%2Fangularjs%2Fcontent-block%2Fcontent-block.directive.html%3Fcb%3D850e76cd9c654537ca47d425e7a85c78&p1=500&p2=Internal%20Server%20Error"
I could fix (?) it by removing some lines from .htaccess in the /plugins folder:
# Serve HTML files as text/html mime type - Note: requires mod_mime apache module! <IfModule mod_mime.c> AddHandler text/html .html AddHandler text/html .htm </IfModule>
