I have a local installation of wordpress for testing and a production server.
I use XMLRPC to create custom posts with custom fields and everything works flawlessly on my local installation BUT it doesn't work for the production server. Custom Fields are not saved, I checked the table and it doesn't store it.
Is related to the underscores present in the start of the custom fields, for example:
I have tried to store a custom field
al_listing_price and it was saved in the database.
Where I can disable that behavior so it allow to post prefixed underscore custom fields?
