Nginx Custom Configuration disappears after save

[highwaycat]

The problem occurs under the Web Server tab, at Advanced configuration.

After saving, and clicking on the start button at the top, the whole content of the textareas disappear after the first semicolon, and only save the remaining part into the nginx.conf.

I am having this problem too. Did anybody find a solution?

Could be full nvram. I use external HDD with custom mounted filesystem and external nginx using opkg (Tomato entware) works awesome. I even compiled my own nginx on router =)
