Error when installing demo content

[keelanfh]

Steps to replicate

1. Start with clean localgov_project install
2. Install localgov_demo

Observed behaviour I see the following error: Everything seems to work fine, and it doesn't seem to cause any actual issues, but it is a bit off-putting.

I seem to remember a while back it being a bug trying to install via the UI (should be addressed though if we can). Could you check if you can install via the command line? drush en localgov_demo

[keelanfh]

Yes, that looks right. When I run that command, I just get this - one warning but no errors.

@finnlewis was it @ekes or @stephen-cox who was looking at this? Its the issue where directories is installing, but search is not set up correctly or something to that effect if I recall.

[stephen-cox]

The Demo module should not be installed through the UI on a fresh install because it will hit the PHP max execution time and max memory limits and crash. We need to make it as clear as possible that the Demo module should be enabled with Drush.

It should be possible to enable with through the UI by setting both memory_limit and max_execution_time to reasonably high numbers, but you don't want to be making these changes permanent and the exact numbers are going to depend on the environment. Installing through Drush is the most reliable method.
