Cannot gather stats! Warning!stat(): stat failed

Today I imported a couple of new products with uRapidFlow in Magento 2.1.2. I ran the import with the option Action on missing image file which was set to WARNING and update image field. It worked fine, but I accidentally forgot to upload the product images.

So basically uRapidFlow added non-existing product images to the database which broke the product edit form in the admin panel.

The temporarily solution was to manipulate ./vendor/magento/module-catalog/Block/Adminhtml/Product/Helper/Form/Gallery/Content.php in vendor around line 142,143.

I basically added is_readable to check if the file exists. Not great, but at least I was able to edit products again and proceed with a permanent fix.

Algolia and Undefined index: store_id

Today I have setup the Algolia Queue Runner ( algolia_queue_runner ) which was working fine for all projects I have worked with before. However, today it was different. The Algolia Queue Runner didn’t work at all. Here is what happened every time when the cronjob was running.

The problem was, one of the store views in Stores > Settings > All Stores was disabled for some reason. After enabling the store view, the problem was fixed.

Delete Quote For Specific Customer In Magento2

Sometimes a quote can be linked with product id’s which doesn’t exists anymore. In some cases it can cause broken MySQL joins. Here is how you can flush the quote for a specific customer in Magento2.

Remove the WHERE clause to flush the quote for all customers.

AWS RDS – You Need (at least one of) The SUPER Privilege(s)

Today I had the opportunity to move a local Magento database to an Amazon RDS. Based on the well-documented article Creating a DB Instance Running the MySQL Database Engine I was optimistic to finish the migration pretty soon. But as you know, there is always something that goes wrong.

After creating the database instance class ( db.m3.large ) I have decided to proceed with some test imports before I change any database credentials in Magento.

Good decision because the first import didn’t run through.

I was able to fix the problem by adding the missing parameter log_bin_trust_function_creators as explained here. Before the next import I had to delete the database and create a new one.

Unfortunately there was another problem with a DEFINER which tried to create a trigger as a different user. On Amazon RDS only a user with SUPER privileges can do that. Therefore, I had to remove the DEFINER from the MySQL schema you see below.

That’s it. Now I was able to import my DB on Amazon RDS without errors.


We’re sorry, an error has occurred while generating this email

Today, I was dealing with the following error message on one of our Magento2 production environment.

After spending 2 hours trying to find the source of the problem in our custom modules, I was able to fix the issue by disabling the core module Magento_SampleData.

What is this module for? This module gives you different sample data ( CMS, Catalog, Customers ) which is useful during development and testing phase. For your production environment it is not necessary and also not recommended to have it installed, as you can read here.

Reset Administrator User Password in Magento 2

Magento 2 comes with a CLI that allows you to create a new temporary administrator user within few seconds. Change to the directory where your Magento installation ( such as app or bin folder ) is located and run the following command to create a user support with password 8cd98f00b20.


Now you can go to System > Permissions > All Users and update other users credentials.
