Server Crash (0.8.2) when uploading topic thumbnail

[jongarrison]

I see this error in the logs before a crash and server restart when trying to upload a topic thumbnail:

10/11 15:23 [17286] - error: Error: Unknown arguments configuration,120,120

Anyone have any ideas? I tested this with the same results on two different 0.8.2 installs running on ubuntu and os x.

Maybe it could be a missing relative path for your forum in your config.json.

Thanks for the tip, I am missing relative_path in my config.json but it looks like relative_path was deprecated about a year ago: https://community.nodebb.org/topic/3392/config-json-updated-base_url-and-relative_path-no-longer-exist

@jongarrison I need it for my notifications to work (at least in 0.8.x). By the way, why don't you simply upgrade to NodeBB 0.9.x (lwip was removed there).

Check this out:

[jongarrison]

Do you have an example of what relative_path should look like? I have two projects right now, one I can update to 0.9, but the other one needs to stay 0.8.2 for now. What is relative_path supposed to be doing?

Is this proper placement:

{
"url": "http://localhost:4567",
"secret": "",
"database": "",
"relative_path": "",
"mongo": {
    "host": "",
    "port": "",
    "username": "",
    "password": "",
    "database": ""
   }
}

Thanks again!

Separately, in 0.9.0, this error message pops up when trying to upload a topic thumbnail:

There is no error in the nodebb logs.

So it appears topic thumbnails do not work in 0.8.2 or 0.9.0

Same error with persona theme and nodebb 0.9.3.
