Since updating AJAX Search Pro, my search results have been acting up. I have sorted out most of the issues, but the main one I have is that my isotopic search results at https://os2int.com/toolbox are not open by default (before the update, the results would autoload to show the 20 most recent posts).
It is a known issue with the most recent release. Luckily there is a very simple fix. On the Compatibility options submenu, just change the javascript source to “Minified”: https://i.imgur.com/NP1NkHj.png
Then clear all of your cache, and it should be fine afterwards.
