It sure looks like PMMV to me. Pepper Mild Mottle Virus (aka PMMoV. See link below of additional pics and the Hot Pepper forum here for more discussions.

Recommendation is to pull and dispose of the plant away from the garden as it can be spread by contact from plant to plant or hand to plant. It is a seed borne virus so the use of only disinfected or treated seeds is recommended.

Thanks. I pulled the plant out. Is it okay to plant another pepper in the same spot?

I wouldn't. I'd plant something not in the pepper family instead. But you can try. If it turns bad also then the virus is already in the soil there and it will need to be dormant for a season to die off.

If from the same seed source and you grew these from seed yourself then the odds are the rest of the seed is also contaminated and should be pitched.

Ugh.. Really stinks loosing a plant.. I just hope my tomatoes don't get infected. They are doing so well.
