I am new to magento2. Have worked enough on magento 1 but this is my first project with magento 2.2 and i ran into issue.
I have magento 2.2 setup and installed template monster theme. Everything was working fine. Then i started adding content of my own and created few categories. Later i realize i didn't want 1 root category which i created. so i deleted it and then i started getting this error on front side. Back-end is working perfect.
Here is a full list of errors i am getting.
I already tried disabling theme and extensions. None of them work. Basically magento is looking for category id 0 which is not there as it always start with 1 in db. I am not sure how to solve or dont know where to see.
Any guidance will be helpful.
