I just tried to install a fresh WB 2.10 to a new site and it all went OK, but when I access the admin and try to create / edit a page, no modules appear. For example no WYSIWYG editor, no form module editor, etc. You can see the attached image.
I upgraded the PHP version of the server to 5.6 and at first I had a problem with a MySQL extension, so I guess there is some other extension that I need to install but don't know which?
I installed WB 2.10 on a subdomain on the same server and configured the subdomain to use php 7 and it works correctly there. BUT I can't upgrade to php7 on my main server as I have many other scripts that don't support it yet.
