Reindex failing on save

Hello,

Im having some troubles on reindexing tables. Once i hit “reindex table” it shows the total amount of products, the ajax response seems fine “{“success”:true,”data”:{“offset”:0,”start”:false,”found_posts”:137}}”, but when i save, the “products in index” count goes back to 0, and i get ” Please go to plugins settings page and click on “Reindex table” button.” on the front end.

The page I need help with: [log in to see the link]
