Hi, I'm Shox from Mageplaza. This problem occurs because you doesn't have root category in mageplaza_blog_table: https://prnt.sc/tnqn4b. Please add root category in your db and check again.

Hi @asifsomy ,

Please try this solution of Bang512 , it's working for me : https://github.com/mageplaza/magento-2-blog/issues/271 and set category_id : 1

Hi,

I faced the same issue in Magento 2.4.1 Cloud Environment. Root category_id in mageplaza_blog_category table was 2.

I just updated it with SQL command.

UPDATE mageplaza_blog_category SET category_id = 1 WHERE category_id = 2;
