How to solve cron problem in WordPress?

I am working with associations using the paid membership Pro plugin but I noticed that the subscriptions are not expiring, I thought that at the beginning it was a plugin problem but I realized that even disabling plugins and themes my posts with scheduling data are not published. Could someone help me how I could do this, I did the test passed in the wp-config function – define (‘ALTERNATE_WP_CRON’, true); everything seems to work but I see that my url is being changed causing an impact on my SEO for being an unfriendly url. Could someone help me on how can I adjust this cron problem on my wordpress?
