**Your software**  
My Mautic version is: 2.16.3  
My PHP version is: 7.3  
My Database type and version is: MariaDB and it is 10.4 version.

**Your problem**  
My problem is: I can’t edit any focus items, once in builder I get a 500 error (unsure if this is related or a different issue). Also once a user signs up my email sequence doesn’t start.

These errors are showing in the log:

[2020-11-18 17:20:01] mautic.ERROR: CAMPAIGN: An exception occurred while executing ‘REPLACE INTO mauaf\_campaign\_lead\_event\_failed\_log( `log_id`, `date_added`, `reason`) SELECT id, :dateAdded as date\_added, :message as reason from mauaf\_campaign\_lead\_event\_log WHERE is\_scheduled = 1 AND lead\_id = :contactId AND campaign\_id = :campaignId AND rotation = :rotation’: You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near ‘:dateAdded as date\_added, :message as reason from mauaf\_campaign\_lead\_event\_l…’ at line 2

Steps I have tried to fix the problem: Cleared Mautic Cache, tried to update schema, restored update on server from when Mautic was last working.
