Everything worked very well until I loaded the Piwigo-OpenStreetMap plugin. When I completed the configuration page, the following error came up in the header area...

Warning: Cannot modify header information - headers already sent by
(output started at /.../Piwigo15/plugins/piwigo-openstreetmap/admin/admin_config.php:201)
in /.../Piwigo15/include/page_header.php on line 99

I was relieved to find that the maps displayed in all the right ways in all the forms. However, when I clicked on any of the search icons or menu items, the system crashed with the following error message...

Fatal error: Uncaught TypeError: Cannot access offset of type string on string in

Much as I like the greatly improved search function, particularly the search by ratio to pull up my panoramas, I would not be taking the update to Piwigo 15 until this plugin problem is resolved.
