1. Open Terminal on your Mac and type in `docker exec -it devkinsta_fpm bash `

2. Type in `apt-get update && apt-get upgrade && apt-get install nano`. You will be prompted to type Y. This step will install `nano` so you can edit the file.

3. Then type in `nano /etc/php/7.3/fpm/php.ini`. You may need to change the 7.3 to another version. Match this with the version the site is on on DevKinsta.

4. There’s quite a bit here but what you’re looking for is `post_max_size`. To do a search, press control+w on your keyboard - type post\_max\_size - then enter.

5. Change this to your desired value. `post_max_size = 64M` should do it. Exit with control+x and press Y to save.

6. Type `exit` then `docker restart devkinsta_fpm`

Should be all good from there! Let me know if you have any questions about any steps here.
