mekici Search works ok for me. Just in case this is what you’re experiencing... due to performance issues for the time being, you can’t search post titles in Flarum. Your keyword has to match something in the body of a post. But, this has nothing to do with this views extension.
But, anyone out there, hopefully someone can duplicate my issue mentioned above... with the latest version of this views extension installed, and the abbreviation setting turned on, and the Pages extension with a page created, go to the page. Then click the built in back button top left of forum. Do the discussions load? Mine do not. I deactivated all extensions but these couple too. Still not fixed. Sigh.
