Problem:
Customer reported that number search is not working properly Solution:
In the "Using this comparison" field it was set as 'equal to" https://snipboard.io/K5xH8m.jpg.
Switching to the'like' option instead seems to have fixed the issue.
Solution:
If you see the fatal error with PHP 8.1.x then please make sure that for your custom taxonomy or post types the placeholder for labels should be added with required placeholder %s where applicable.
