Layout definitions

[AngeloVenera]

Hello everyone,

I have a problem in this plugin, if I leave in "Layout definitions" only the default one I can click on the search modification button, and the advanced search page appears, as soon as I add a second or third layout and change the view of my documents, as soon as I click on edit search I get this message:
"Zend_Controller_Dispatcher_Exception: Invalid controller specified (find&layout=2) in /var/www/html/omeka-2.7/application/libraries/Zend/Controller/Dispatcher/Standard.php:248
Stack trace:
#0 /var/www/html/omeka-2.7/application/libraries/Zend/Controller/Front.php(954): Zend_Controller_Dispatcher_Standard->dispatch(Object(Zend_Controller_Request_Http), Object(Zend_Controller_Response_Http))
#1 /var/www/html/omeka-2.7/application/libraries/Zend/Application/Bootstrap/Bootstrap.php(105): Zend_Controller_Front->dispatch()

#4 /var/www/html/omeka-2.7/index.php(23): Omeka_Application->run()
#5 {main}"

seems to be missing the link https://ebooks.unict.it/omeka/find/advanced. How to solve it?
