If you get this error, then you've updated Ninja Forms plugin to version 3.0 before updating Vamtam Elements bundled plugin to version 1.0.2:

Fatal error: Call to a member function get_all() on a non-object in /nfsmnt/hosting2_2/4/c/4c5b1830-63a6-4323-8d0c-b74560661f36/hairless.sk/web/wp-content/plugins/vamtam-elements-a/vamtam-elements.php on line 145

In this case, please follow the solution below:

  • Upload the attached replacement for the affected file via FTP in wp-content/plugins/vamtam-elements-a/vamtam-elements.php
  • In addition to that, we recommend that you revert your Ninja Forms install to 2.9 for the time being (Forms/Settings/Advanced - click the "Roll back" button). The Ninja Forms Layout Master plugin which we use for the demo content is not yet compatible with NF 3.0. As it is not developed by us, we are waiting on the plugin's developer to release an update.
