Why Aren’t Shopware Plugins Appearing in the Shopware Admin Panel, and How Can You Resolve This?

If you are experiencing issues with Shopware plugins not appearing in your system, it can disrupt your e-commerce store’s functionality. This guide will walk you through potential

Common Causes of Missing Shopware Plugins

1. Plugin Crash Issue:

The issue may be caused by a plugin crash or incompatibility. To resolve this, disable each plugin directly through the database by setting the “active” column in the plugin table to 0. Then, enable the plugins one by one to identify the problematic ones.

2. COMPOSER_HOME Path Issue:

Check your .env file for the correct Composer path, as it may be incorrect. Fix it if necessary.

How to Fix Shopware Plugins Not Showing?

Step 1: Deactivate Plugins in the Database

Access the plugins table in your database and manually update it to deactivate all plugins. This can reset plugin statuses and help identify conflicts.

Step 2: Check for Network Errors

Verify your system for any network-related issues that could prevent the plugins from loading.

Step 3: Resolve Foreign Key Constraints

If the issue persists and you see a foreign key constraint error, follow these steps:

1. Identify the Missing Table

Run the following command to check if the referenced table exists in the database:

SELECT TABLE_NAME, COLUMN_NAME, CONSTRAINT_NAME, REFERENCED_TABLE_NAME, REFERENCED_COLUMN_NAME  
FROM INFORMATION_SCHEMA.KEY_COLUMN_USAGE  
WHERE REFERENCED_TABLE_NAME = 'plugin_old_ver'  
AND TABLE_SCHEMA = 'shopware_demo';

SELECT TABLE_NAME, COLUMN_NAME, CONSTRAINT_NAME, REFERENCED_TABLE_NAME, REFERENCED_COLUMN_NAME

FROM INFORMATION_SCHEMA.KEY_COLUMN_USAGE

WHERE REFERENCED_TABLE_NAME = 'plugin_old_ver'

AND TABLE_SCHEMA = 'shopware_demo';

2. Remove the Foreign Key Constraint

If the table does not exist, remove the foreign key reference using this command:

ALTER TABLE referencing_table_name  

DROP FOREIGN KEY fk_constraint_name;

ALTER TABLE referencing_table_name

DROP FOREIGN KEY fk_constraint_name;

Example:

ALTER TABLE plugin_translation  

DROP FOREIGN KEY `fk.plugin_translation.plugin_id`;

ALTER TABLE plugin_translation

DROP FOREIGN KEY `fk.plugin_translation.plugin_id`;
