Temando_Shipping module might have added an EAV attribute already with a specific source model that no longer exists. This could generate an exception Class TemandoShippingModelSourcePackagingType does not exist when trying to edit product. To fix this, run the following SQL query in your database:

DELETE FROM `eav_attribute` WHERE `source_model` LIKE '%Temando%'

Worked for me, thanks a lot!!!

nice solution, it helped me to save a lot of time.
I found another solution: we only need to set NULL for source_model instead of deleting attributes.

Worked for me too as the others! Just 3 rows effected, saved me a headache thank you!

Just throwing my hat in the ring: I have seen this problem on 2.3.4. after disabling Temando_Shipping. I re-enabled it and the problem went away. Would prefer not to have that module active but it is what it is.

Experiencing same issue in 2.3.4 after disabling Temando_Shipping.

Ran the query on my magento database: SELECT * FROM eav_attribute WHERE source_model LIKE "%Temando%"

Set the 3 values to "NULL". Now I can edit products again (and leave Temando_Shipping disabled).

[densen45]

I experienced the same issue in 2.3.5 (Temando_ShippingRemover is disabled).

Setting the source_model for the three Temando's eav_attributes to NULL solved this issue.

Thanks to all who have pointed this out!
