'BLOB/TEXT column 'fb_userid' used in key specification without a key length SQL=ALTER TABLE `#__comprofiler` CHANGE `fb_userid` `fb_userid` text'
I have tried editing this field in phpadmin with the same query result

You've CB Connect or previously Facebook Connect field present, but you don't have the plugin installed. Either install CB Connect or delete the fb_userid field in CB > Field Management.

but this fails to install, as does the cbpaidsubsbot joomlaplugin_cbpaidsubsbot-4.1.0+build.2017.05.19.15.39.30.520d1fe23.zip
Also, the 'Your Profile' and 'Edit Profile' menu items link to a blank page; (I have edited these menu items to display the correct menu-types, which were missing after upgrade)

You installed the main CBSubs plugin, but didn't update anything else. Use the preset below to download and install all of CBSubs as a single package or select what plugins and extensions you need from the downloads page.

OK, thanks for that; I'm sure I tried that earlier and it failed;
but i still have a CB Log-in menu whose 'profile' and 'edit profile' links generate blank pages

See our FAQ below regarding blank pages. You likely have an incompatible plugin installed causing problems.

Thanks; it eventually turned out to be the old CB Captcha plugin that I hadn't disabled (plus and outdated xmap component) I can now view the profiles but am having trouble with CB Privacy; I have installed the latest version and Filezilla shows it all as updated as far as I can see, and the CB Tools check shows that databases as updated, but CB's plug-in management shows it as still version 1.3 and when editing the CB Antispam fields the CB Privacy integration tab shows '' is not Published'.
I am also struggling to get the antispam to display...

Download and install latest CB Privacy below through Joomlas extension manager.

Next navigate to CB > Plugin Management to verify its version. If it's still not showing up to date you many have permission problems preventing the files replacing.
