Barcode field gone

I updated to 3.6.0 from 3.5.4
All seemed to go well untill i found that the barcode field in products is gone.
Barcodes are shown in the products list view.

How to correct this?

I also updated from 3.5.2 to 3.6.0, and still have the barcode fields. The new product screen is even improved and has also the barcode field.
Have another dolibarr installation in 3.5.4, will update it to 3.6.0 to try to simulate your problem.

Thanks to Francis Appels we found that the htdocs/product/fiche.php as delivered in the .tgz generates this problem. The version in .zip works fine.
One remaining problem however: adding a barcode value in existing records using the button next to the barcode value field gives a blank screen. Work-a-round here is using the change a whole record procedure.

Issue can be closed.
Thanks again Francis.

If you want to be sure your tgz is correct, SourceForge provides md5 checksums,
