You must have encountered a popup notification in the admin panel stating, “One or more indexers are invalid.”
Annoying right? Well, not anymore since we have a solution for you to avoid this.
Before jumping to the solution, let’s first understand why this error occurs in Magento 2.
What Does the Error Mean?
The “One or more indexers are invalid” error occurs generally after modifying products, changing category structure, updating stock and inventory or modifying price/attribute.
Magento indexes large amounts of data to optimize performance.
When a certain update occurs from your end, Magento initiates reindexing to update changes in the database tables. However, this process can sometimes lead to “One or more indexers are invalid. Make sure your Magento cron job is running” error.
To avoid this error, you will have to reindex manually for the desired changes to appear in the admin panel.
Possible Fixes for “One or More Indexers are Invalid” in Magento 2
Step 1 : Check Indexer Status
First, verify the indexer status by running the below command in the CLI. It will generate the status of all indexers.
php bin/magento indexer:statusThe status would be one of the following:
- Ready – If the indexer is up to date, ready status will be returned by the command.
- Processing – It means the indexer is updating currently.
- Invalid – If Invalid state is returned – that means the indexer should be reindexed and that’s why the issue is arriving.
Step 2 : Reindex All Indexers
If indexers are invalid, you can fix that using the below command:
php bin/magento indexer:reindexOptional Step : Check Cron Jobs
If the indexers are invalid, there are higher chances that the cron jobs are not running properly because the cron job handles indexing in Magento 2.
Once all the indexers get reindexed, the cron job should be created for the same. However, sometimes this might be missing. In such case, you can install this missing cron jobs following the below command:
php bin/magento cron:installYou can verify whether the cron job is running properly or not by checking its status.
Check cron job status:
php bin/magento cron:statusIf cron jobs are not running then use the below command:
php bin/magento cron:runStep 3: Verify the fix
After reindexing and running cron jobs, to know whether the “One or More Indexers are Invalid” issue is resolved or not – follow the below steps.
Run the following command in the Magento root directory:
php bin/magento indexer:statusIf all indexers return “Ready” state, the issue is fixed!
You can check the same in the admin panel as well.
- Refresh the Magento Admin Panel.
- Go to System → Index Management and ensure all indexers show Ready (not “Reindex Required”).
- If the warning “One or more indexers are invalid” disappears, it’s resolved.
