This morning, I accidentally started to delete items on my site via ftp. I meant to delete one item, but I slipped a finger and started to delete the root. It only was deleting for a couple seconds before I stopped it, but enough time to screw something up. I restored the files to the best of my knowledge, and everything is seeming to work but one thing. Coupon Codes do not work. When you select what categories in the admin you want the coupon to be applied to, it does not keep the settings you choose. They get unchecked right after you leave the page.
I had a complete backup and restored and had my hosting do a restore also. I also restored my database. Still no fix. The coupons were working on July 3rd.
This store in in opencart and was working perfectly until now. The only issue that I know of is the coupons.
