Enabling or disabling CiviCRM extensions in the admin page does not work after activating civimobileapi
This problem has been encountered with both a Wordpress and a Drupal CMS setup with CiviMobileAPI 6.1.2:
- Wordpress: https://civicrm.stackexchange.com/q/43471/14256
- Drupal: https://civicrm.stackexchange.com/q/43596/14256
Unfortunately, there is no error message I could share.
