Closed 3 years ago.

I am getting following error on Magento 2.2 after upgrading from 2.1.9

1 exception(s):
Exception #0 (InvalidArgumentException): Unable to unserialise value.

The string on which this error is occurring is as below

a:6:{s:4:"type";s:44:"Amasty\Xlanding\Model\Rule\Condition\Combine";s:9:"attribute";N;s:8:"operator";N;s:5:"value";s:1:"1";s:18:"is_value_processed";N;s:10:"aggregator";s:3:"all";}

Any help will be appreciated!

Answer 1

Looks like the extension Amasty_Xlanding is not compatible some how with Magento 2.1.9.

Disable the extension and ask Amasty guys for the latest version of this extension.

You can disable any extension following the steps described in here.

You can also use the command line tool:

php bin/magento module:disable Amasty_Xlanding
