Hi
this is the Spanish public sector add-on, its weird you have installed it.... You won't need anything from this packet so best it's to take it off. Why was it installed in the first place?
Your error message is within a class that belong to it (hrpbse) so removing the add-on is likely to remove your error.
spanish public sector solution well is only for public sector entities here in Spain that behave very differently than the private sector.
best
Antoine
