<script>
    require([
        'jquery'
        ,'domReady!'
    ], function ($) {
         console.log('whatever');
    });
</script>

Of course, you can skip listening to domReady event! Just remove the domReady line, like this:

<script>
    require([
        'jquery'
    ], function ($) {
         console.log('whatever');
    });
</script>

<?= $block->getToolbarHtml() ?>

with

<?= $block->getChildBlock('toolbar')->setIsBottom(true)->toHtml() ?>.

This should solve the problem, your pager should now be visible again.

php bin/magento config:set system/security/max_session_size_admin 0

The problem here is that the values from the checkout are not being passed over to PayPal. The solution is to install the CopeX/PaypalFix. After installation, clear your caches, reload the checkout and you should be done.

{{block class="Magento\\Cms\\Block\\Block" block_id="block_identifier"}}

Run this from the Magento 2 root directory to disable maintenance mode for your IP:

php bin/magento maintenance:enable --ip="12.345.678.123"

Deactive your IP again:

php bin/magento maintenance:disable --ip="12.345.678.123"

$session->clearQuote(); // before
//$session->clearQuote(); // after

You can now reload the page as often as you like. Make sure to undo your changes when you are done!

php bin/magento maintenance:enable --ip="12.345.678.123"

Undo:

php bin/magento maintenance:disable --ip="12.345.678.123"

In a nutshell: A cache warmer calls all your store URLs at a predefined time. Doing so, it makes sure that the URLs are put into the cache automatically. This in return results in your Magento shop running at optimal speed all the time, without any manual interaction (from you or your customers). No more clicking all your product pages just to put them into your cache!

I am offering the Magento cache warmer for $100 excluding VAT. This includes the setup on your system. Are you interested in the Magento Cache warmer or would you like to ask some questions? Just get in touch to place an order or to ask some cache warmer questions.

The Magento cache warmer runs on Magento 1 and Magento 2 and works with all modern caching systems.

After installation, run these 2 commands:

php bin/magento cache:flush
php bin/magento cache:clean

Now just reindex as usual, the rewrites will be included.
