Magento 2 : One or more indexers are invalid. Make sure your Magento cron job is running

Question

I find error admin "One or more indexers are invalid. Make sure your Magento cron job is running"

I've run command Re-Index php bin / magento indexer: reindex but appeared issue another Fatal error: Class 'Locale' not found in / home / qyivmqoz / public_html / magento2 / vendor / Magento / framework / Locale / Bund le / DataBundle php on line 64

I use PHP 5.6 and MySQL 5.6

Is there a solution for my problem.

Answer 1

In order to fix the issue

One or more indexers are invalid. Make sure your Magento cron job is running

Just run the query:

UPDATE indexer_state SET status = 'valid'

And the error

Fatal error: Class 'Locale' not found

is due to missing intl extension.

Make sure if you have PHP intl extension installed. You can simply check either from phpinfo() or from CLI as

php -m | grep intl
