I might be wrong, but i think i have came across a bug.
Follow up story:
I need to make hotspot signup only show one specific profile, not all of them. I found on https://wiki.mikrotik.com/wiki/User_Man ... ser_Signup
that i can do that by custom sign up page.
When i navigate to the root of router i see two directories: "umfiles" and "flash".
Under umfiles directory are all default templates for sign up page. I can easily change all the template as custom as i need them and everything works nicely. But the problem is that after router reboot umfiles folder is gone. It just get's automatically deleted. And when i request signup page the umfiles folder gets created again, but it's back to default.
MikroTik wiki https://wiki.mikrotik.com/wiki/Manual:System/File
says that everything, but "flash" folder is stored in RAM folder. Which explains why "umfiles" folder get's deleted.
How can i keep umfiles folder on my mikrotik, so after reboot hotspot would still use my custom pages?
I know it's a shitty solution, but i can probably store my modifies umfiles folder in "flash" directory and make a script which will copy /flash/umfiles directory to /umfiles on mirkotik startup. Can anyone please help to make a script to achieve that? :/
