Historically, each time we released an update to the Showcase IDX Search (which is used by the Showcase IDX Wordpress Plugin), the search functionality would break on Wordpress sites with caching enabled until you manually cleared your cache. This was frustrating and annoying for our customers.
We are extremely pleased to announce that we've developed a solution to this issue! We launched the fix for the caching issue a few hours after the updates that we shipped last week, and can report that we had no reports of any issues, meaning that the fixes are working great!
There should no longer be a need for you to clear your Wordpress caches when we make updates. One less thing to worry about!
