I am running Panagea wordpress on https://toursthailand.nl. When adding locations (I have around 15 in Thailand) and adding them to a tour, the whole system crashes because it's eating up too much CPU. I have added 3 screenshots to show what's the problem.
1. Adding location (this works without a problem)
2. Adding location to the tour and saving (this is the issue, CPU maximizes and my website stops working instantly)
Deleting the location and creating a new one with the same name works, but I don't want to have to delete the location and add a new one every time I add a tour. Also because the post ID changes and that means changing links everywhere on my website. Can you please help me and let me know how to fix this?
