OMP don't show feature and new release books in homepage

Hello, I’m using OMP 3.1.2-1.with Debian10, PHP7.2 and MariaDB.
OMP don’t show Feature Book and New Releases in frontpage. I have this error from Apache Log:

[php7:warn] [pid 18605] [client xxxxx:57395] PHP Warning: Declaration of PublicationFormatCategoryGridDataProvider::loadData($request, $filter = NULL) should be compatible with SubmissionFilesCategoryGridDataProvider::loadData() in /web/htdocs/libros/controllers/grid/catalogEntry/PublicationFormatCategoryGridDataProvider.inc.php on line 19, referer: http://libros.uanl.mx/index.php/catalogo/workflow/index/1/5

I have another OMP installation, on another server and if it shows the books in frontpage.
Any ideas?
