Can you post a full stack trace of the error please?

[yosirn]

I don't think I can . it throws this error instead Error PDO::quote() expects parameter 1 to be string, object given, /MyApp/vendor/doctrine/dbal/lib/Doctrine/DBAL/Driver/PDOConnection.php:92

[aimeos]

Can you record a screen cast what you do when the error occurs?

[yosirn]

I just click delete item and confirm , the action get submitted but return this error after a while. I don't know what the error may be as I didn't change anything from the demo app except some locale configs

[aimeos]

Can you please have a look into the Log panel? There should be a stack trace of the error

[yosirn]

Only some items produce this error some could be deleted. please find bellow my today's log if that may help.

log-18-05.log

[aimeos]

There's no error related to that problem :-/ Which items could you delete and which ones not?

[aimeos]

Think, we've found the problem. Can you execute composer req aimeos/aimeos-core:2019.10.x-dev and test if it works now?

[yosirn]

Products I wasn't able delete are IDs 8,11,12 from the demo. this fixed it now they can be deleted Thanks

[aimeos]

New release of the core (2019.10.26) is tagged. Thank you very much for your help!!! :-)
