CiviMobile: Can't log into CiviCRM using CiviMobile
There could be few reasons:
1. Please check the correct extension is installed. You need to install CiviMobileAPI extension (https://civicrm.org/extensions/civimobileapi), not CiviMobile. You can find installation steps here https://civimobile.agiliway.com/#how-to-start.


What CMS do you use?


If you use Drupal or Joomla then there should be no problem. Please check that you specify proper URL paying attention to http/https and www or without www.
if you use WP then there is a bug in core CiviCRM API which prevents API works correctly. Please start reading here for more details https://github.com/civicrm/civicrm-core/pull/12813#issuecomment-428152827
As an immediate solution, we are preparing API fix patch WP clients. It will include our quick fix and instruction how to install in. 
Please write us at civicrm@agiliway.com IF you use WP.



If it still does not work then please write us (civicrm@agiliway.com) so we can investigate the problem. 

Thank you,
