I was at 2.0.12 and had issues upgrading to 2.0.14.

Updating Groupjive and cbsubs overcame the upgrade error, but I have 2 issues:

When looking t user details, I get this error:
1064 You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '' at line 12 SQL=SELECT COUNT( a.`id` ) FROM `#__comprofiler_plugin_activity` AS a LEFT JOIN `#__comprofiler_plugin_activity_hidden` AS b ON b.`type` = 'activity' AND b.`item` = a.`id` AND b.`user_id` = 236 LEFT JOIN `#__comprofiler` AS c ON c.`id` = a.`user_id` LEFT JOIN `#__users` AS d ON d.`id` = c.`id` LEFT JOIN `#__groupjive_groups` AS gj_g ON a.`type` = 'groupjive' AND ( ( a.`subtype` = 'group' AND a.`item` = gj_g.`id` ) OR ( a.`subtype` != 'group' AND a.`parent` = gj_g.`id` ) ) WHERE b.`id` IS NULL AND c.`approved` = 1 AND c.`confirmed` = 1 AND d.`block` = 0 AND ( a.`user_id` = 241 OR a.`parent` = 241 ) AND

When running ' Check Community Builder User Fields Database with strict column types' tool, I get the following errors:
CB fields data storage database structure differences:
Table #__comprofiler Column cb_phone type is varchar(255) instead of text
Table #__comprofiler Column cb_mobile type is varchar(255) instead of text
Table #__comprofiler Column cb_atactivity type is varchar(255) instead of text

clicking fix says it resolves, but error stays.

I have been going through each plugin, downloading those versions in red and updating them, which seems to have solved the first error.

Many of the plugins are still in red after updating.

The second error now shows:

Table #__comprofiler Column cb_phone type is varchar(255) instead of text
Table #__comprofiler Column cb_mobile type is varchar(255) instead of text
Table #__comprofiler Column tumblr_userid type is varchar(50) instead of varchar(255)
Table #__comprofiler Column cb_atactivity type is varchar(255) instead of text

Running 'Click here to fix (adjust) all CB fields data storage database differences listed above'

I get error:

An error has occurred.
1170 BLOB/TEXT column 'cb_phone' used in key specification without a key length SQL=ALTER TABLE `#__comprofiler` CHANGE `cb_phone` `cb_phone` text

And re-running 'Check Community Builder User Fields Database with strict column types' still gives
CB fields data storage database structure differences:
Table #__comprofiler Column cb_phone type is varchar(255) instead of text
Table #__comprofiler Column cb_mobile type is varchar(255) instead of text
Table #__comprofiler Column cb_atactivity type is varchar(255) instead of text

Great - that sorted it.
