Tags not appearing in side bar even though showing under post

From https://www.seorankings.com/limit-wordpress-tag-cloud-to-help-control-pagerank-flow the limit is 45

Thanks Richard. Is there a way to increase the number? Our blog has just started and we have blown the limit already. We are bound to want many more.

I lost my post when I went back to look for it, but good old google allowed me to find it again.

If you are using the Tag Could widget you can’t change the number of ‘top 45’ tags. But you can put the Template Tag, wp_tag_cloud() in your sidebar.php or consider downloading and installing Otto’s PHP Code Widget, then something like this code in one of those widgets:

<?php wp_tag_cloud('number=500'); ?>

of course replace number=500 with how many you want.

there are also plugins such as ‘configurable tag cloud’ https://www.ads-software.com/extend/plugins/configurable-tag-cloud-widget/ or others that allow you to change these parameters.
