Re: Error during unserialization

Hi @bcphang


Seems like this is known bug and it is already fixed in SUPEE-8788 patch.


To resolve the issue , kindly install this patch in your magento version and that will solve the error.


Here is the reference link for how to install/apply patch on the existing magento application -

Re: Error during unserialization

Hi @ManthanDave,


The Magento version is CE

It should already have the SUPEE-8788 applied in the version itself.


So I guess it should be a different issue?
