Repair a site with an API Connection/Database Cron

I have a WordPress website that integrates with the Product Hunt API, and uses Product Hunt's data to display the lowest 100 upvoted products in different categories. The data is displayed by a number of time periods (last 30 days, current year, last year, all time). There is an issue with the API or the chron such that only some categories are pulling data - currently only some categories and time periods display projects correctly. Current site is: [login to view URL] If you look at the "TECH" category for "CURRENT YEAR", you will see data, but "LAST 30 DAYS" shows no data. There are similar issues in other categories. This site worked well for many months, so I do not expect this is a significant development challenge. My guess is that either something is wrong with the database, or there is an issue with the cron settings. I would also like to implement a feature whereby when a Product Hunt project is added to our list, an automatic tweet is sent with a pre-written text. Similar to how Product Hunt automatically tweets/sends announcements when users post to Product Hunt. NOTE: Applicant should be familiar with Product Hunt and understand their API (link below) [login to view URL] Let me know if you have questions. Thank you!
