I'm trying to use Civimobile but can't sign-on. I get "unknown error". I'm using WordPress 5.2.2, PHP 7.2 and CiviCRM 5.15.1. I installed Civi CRM Api Fix. plugin 1.0.0, and CiviMobileAPI extension 4.0.
I followed the advice in this post Does CiviMobileAPI generate any logs? and install the CiviCRM WP REST API plug-in. I also renamed the extension directory name so it is just "com.agiliway.civimobileapi".
What else should I do?
