Ok, I found it! And I saw what the developper said, they repaired it as I understood:
forge.joomlapolis.com/issues/5246
. But few questions:
the problem was in this function:
Code:
preg_replace( '/[^-a-zA-Z0-9_]/', '', pathinfo( $value['name'], PATHINFO_FILENAME ) )
so maybe it's possible to change it like this:
Code:
preg_replace( '/*/', '', pathinfo( $value['name'], PATHINFO_FILENAME ) )
so that it can work with any symbol (latin, cyrillic)?
