Learndash Not Updating Properly

Hi,

I’ve been having issues with Learndash. Two key issues I’ve experienced:
1. When I add a course category, it just loads forever. However, when I refresh it, the update is reflected. But to add categories, I had to always refresh after inputting details and clicking create.
2. When I try to upload a featured image in a course, it’s not working. I always get an “Updating failed” result and the course just ‘updates’ and ‘saves’ forever. When I refresh it, it doesn’t work.

I’ve tried deactivating some plugins but it didn’t do anything. Hoping to get solutions for this. Thanks!
