I have a site which is making very good use of the Advanced Post Creation add-on. The only issue is it does not appear to clear the site cache after a submission is made. This means a user can post a new item but be unable to see it on the site (if they go to the page where such posts are listed).
Is there an action I can employ to force the site cache to refresh after the new post has been saved?
You could use the gform_advancedpostcreation_post_after_creation hook to clear the cache after the post has been created.
You’ll need to contact the developer of the caching/optimization plugin/service your site is using to find out which of their functions you need to call using that hook.
