I just (finally) migrated from Joomla 2.5 and CB 1.9.x to CB 2.0.10 last night. So far, so good.

Now that the migration is done, I am running a bunch of checks on my site, to make sure everything is OK. When I check the CB User Fields using Community Builder => Tools, I get the following:

CB fields data storage database structure differences:

Table #__comprofiler Column fb_userid type is varchar(50) instead of text
Table #__comprofiler Column twitter_userid type is varchar(50) instead of text
Table #__comprofiler Column linkedin_userid type is varchar(50) instead of text
Table #__comprofiler Column windowslive_userid type is varchar(50) instead of text
Table #__comprofiler Column google_userid type is varchar(50) instead of text
Table #__comprofiler Column instagram_userid type is varchar(50) instead of text
Table #__comprofiler Column foursquare_userid type is varchar(50) instead of text
Table #__comprofiler Column github_userid type is varchar(50) instead of text

The CB fields data storage database structure differences can be fixed (adjusted) by clicking here: Click here to fix (adjust) all CB fields data storage database differences listed above (you can also Click here to preview fixing (adjusting) queries in a dry-run), but in all cases you need to backup database first as this adjustment is changing the database structure to match the needed structure for the installed version.

When I try to correct it using CB's included tool, I get the following:

An error has occurred.

1170 BLOB/TEXT column 'fb_userid' used in key specification without a key length SQL=ALTER TABLE `zsbh_comprofiler` CHANGE `fb_userid` `fb_userid` text

Is this something I can address, using the tool, or something like phpMyAdmin?

Thank you!

Ah, OK - I re-installed the plugin, and am all set.

I think I got confused between CB Connections, and CB Connect. I would suggest changing the latter to "CB Social Connect" or something similar in a future release, to help differentiate it more.
