1054 Unknown column 'Array' in 'field list' during item form saving with SP pagebuilder and guest (unlogged) authors

Hi!
I get this error message when i try to submit a form on frontend: 1054Unknown column 'Array' in 'field list'.
Is there any idea, how can I identify the source of error?? 

Hello

1. Switch Joomla DEBUG On Inside global configuration

2. Inside error.php file of your template
templates/TEMPLATE_NAME/error.php
(if you cannot find the switch your frontend template to PROTOSTAR, and edit protostar error.php)
templates/protostar/error.php

Find line: After the above line add:  
3. Visit the form page and submit, note if your form is big or you have many extensions ... browser may freeze for a few seconds because of Joomla Debug
if you get new JS errors and you cannot submit the page then turn Joomla Debug off and replace with
4. Then Copy the full text of error page here,
and then restore your error.php and disable Joomla Debug

This is the error message: Yes I'd like to use with sp pagebuilder.
I'd like to make public submit form for every user. 
created_by field is missing.

Hmm. I checked now. The item is added after I submited the from, but  I get the error message if I submit as guest. If i sbumit as logged in user, everything is perfect.
I think, I don't need the spbuilder record in the database for Flexicontent, but I'm not sure.

So the form is working, but  If the user isn't logged in, there is pagebuilder error message, because the user_id is missing.

Hello

you can ask SP pagebuilder authors to fix / add support for ths case

Give them the SQL query error
and tell them that the user submitting the form is unlogged

Thnx your reply!
Btw is there any method so set a default value for created_by field in Flexicontent?
I'd like assign a specified user (for example John Doe) to created_by field if the user is unlogged, or  use a text field (for example your_nick).
Can this be solved with this component?

Hello

what you suggest of using a default user is interesting but such option does not exist in our configuration

please note that in Flexicontent items manager you can view items owned by user 0 aka guest
plus guests user submiting content can
- have automatic account creation when item form is submitted (field account via submit)
- can be emailed URLs with "edit tokens" that allows editing a specific item only (see configuration inside field account via submit)
