Thanks for the help and advice. I have managed to upgrade to 2.2.15 (from 2.2.14) without any problems. It's a pity about 2.3 but at least I should be secure.
Well I'm nearly there!
Manager is hanging when going to System Settings->Core->Back-end Manager.
Console is showing the following error:
TypeError: 'undefined' is not a constructor (evaluating 'new b[d.xtype||e](d)')
in: ext-all.js
Any help?
Having the menu disappearing too.
MODx 2.3.3 on local Wamp manager and on a remote Apache server.
It seems to be linked to the database I am using for this website.
When I reload it, the menu displays fine.
No errors in the FF console.
Emptying the cache and removing JS and CSS compression did nothing.
