Array to String conversion in at_get_plugins()

All well after installation and creating some generic company contact info. Then I add an individual and set language to 'english uk' and it starts trowing errors (4)

Notice: Array to string conversion in at_get_plugins() (line 38 of {removed}/profiles/erpal/themes/adaptivetheme/at_core/inc/plugins.inc).

I still haven't been able to use Erpal for Service Providers as a showcase and let them do something because of all these type of undefined index or array issues and sql column does not exists errors (relations). I have to show a stable error free presentation soon and I can't. On the back of this I have to explain the importance of using drop-guard which I want to add as part of the solution.

This was a fresh install (few days ago) and had various update notices, the core 7.37 within erpal-7.x-2.2 and a dozen or so modules.
