[Koha] Not Allowed On Shelf Holds

Dear All The error occurs in OPAC even though the following parameters are set: AllowOnShelfHolds is OFF OpacItemHolds is OFF RequestOnOPAC is ON When a title has two items, one is checked out, the other is available, then Koha allows the borrower to place a hold, which is then stored in Koha. This should not be possible, because one of the two items is still available on the shelf. -- -- <https://www.unizwa.edu.om/>  <https://ishraqa.unizwa.edu.om/>  <https://alkhalil.unizwa.edu.om/>  <https://instagram.com/unizwaoman?utm_medium=copy_link>  <https://www.facebook.com/unizwaoman/>  <https://twitter.com/unizwaoman>
