We have a problem with the latest with Woocommerce 3.4.2 and Search and filter pro 2.4.3. When Search and Filter plugin is enabled, we cannot do a number of things in Woocommerce, it either spins in circles trying to save or appears to do nothing. Areas we’ve noticed the issue on is: adding or deleting product categories, modifying product attributes and even modifying wordpress widgets, and searching for new plugins in wordpress does not bring up any results. We also noticed an issue where Smashbaloon’s Instagram feed plugin fails to update with Search and Filter enabled. All issues are non-existent with the plugin disabled. We have not tested with an older version of Search and Filter Pro at this time.
