Dear anhqn,

Corrections that you referred to did not working on new server wich is identical as old.
All documents were copied to the new server along with the corrections. But the slideshow did not work.
The slideshow still does not work as it should work. Navigation does not work, the
block row is not displayed.
And in addition, in the administration part SP Page Builder - Edit Page displayed nothing.

Hi.

I did not hear anything from you for a long time, therefore, I decided to install the site on a new server from scratch .
After the update Helix3, there were problems with the plugin x_menu.
I can not add a menu item in the admin panel. An error is displayed (with the debug enabled)
An error has occurred.
  0 Can not use object of type stdClass as array
.../plugins/system/x_menu_params/x_menu_params.php:30

Would you look at it?

BTW, when debugging is enabled, the slideshow does not work correctly.

Dear dutchman
I fixed for you try add item menu. Please you check again.
Thanks

Thank you. Now it works.
