JUser: :_load: Unable to load user with ID: 64

Greetings,

I'm wondering if you can help me. When I edit a speaker, I'm seeing the warning "JUser: :_load: Unable to load user with ID: 62" reported on a clean installation of Joomla 3.7.0/sermonspeaker 4.6.1

I'm also seeing it on a couple upgraded installations (upgraded from Joomla 2.5.28-->3.7.0

Not sure if it's a concern, or what it might be coming from,
Thanks!

The speaker and sermon entries that come from a fresh installation have user ID set to 62. This user ID is probably a user at the development environment of the author, which may not exist in your installation.
If you want to keep those demo entries, simply change those entries' created-by fields to a user at your system. They warning should go away.

That user used to be the default SuperAdmin user. In some Joomla version that changed to a different or even random number, I don't remember exactly.
Joomla Core has a script which changes the ID in the records to the actual ID of the SuperUser after installation. I need to do something similar for the sample data.

Thanks for replies... Is there a quick way to remove the error?

Sure, either delete the items or change the "created by" field to a valid user.

Thanks so much again Thomas, that took care of it!
