Dexp Masonry grid not working with custom content type


I have build a new Dexp Masonry grid view filtered by my custom content type (dexp_portfolio-rs-rs) and adapted my node--dexp-portfolio-rs-rs--portfolio_masonry.tpl.php file to the field names.

Unfortunately, I can't get any real Masonry display as shown here :

Any help appreciated.

Sorry to insist but stuck in my project.

I get neithe JS not PHP errors.

Masonry items all have the same size.

Please quickly advise.

3 days without even a reply...

Not acceptable for a paid support !

Anybody here ?

Could you please confirm that items should be resized and ordered manually in a Dexp Masonry Grid view ?
