If you are using the "WP Fastest Cache" plugin, you may encounter some issues with FunnelKit when running the funnels.
This is due to aggressive page caching (which is a good thing!), but it can be easily resolved by excluding the offer page URL from the cache plugin.
You need to exclude offer pages by following these instructions:
Step 1: Note down the slug of your offer page from the general settings

By default, the upsell pages slug is "offer". If you had changed the offer pages slug for any reason get the slug from FunnelKit > Settings > General > Permalinks
