Portfolio tab is missing in Fotografie Theme

Hi everyone. It's been a while since we updated our theme on our website so I thought on Monday it would be a good time to do it. Our old theme has the "portfolio" tab on the dashboard and I used that to set up our store a long time ago. I noticed today after changing the theme Monday that our metal shaping tools page was blank, I'm assuming this is because the portfolio tab is missing on the WP dashboard so now I've gone back to the old theme Pheonix. If anyone has any ideas on how to get that tab back so I can resume our webstore I would greatly appreciate it. I know I should be using woocommerce and I may change to that this weekend but in the meantime it would be nice to get that tab back. Thanks for your help. Our website is www.proshaper.com
