Thread:Project:Support desk/Lua error: Cannot create process: proc open(/dev/null): failed to open stream: Operation not permitted/reply (4)

Permissions look fine for /dev/null - crw-rw-rw.

This is strange as I was previously receiving the script error - 'attempt to index field 'text' (a nil value)', now I'm receiving this '/dev/null' error. You can see my previous thread [https://www.mediawiki.org/wiki/Thread:Project:Support_desk/Scribunto_/_Lua_error:_Cannot_create_process. here]

When I try to enable my lua error file - 'Lua error: Cannot create process: proc_open(/mysite/tmp/lua-error.log): failed to open stream: Permission denied'. I tested with 777 permissions on the /tmp/ dir but no luck.

I'm not sure what changed permission wise but I read somewhere it could be my /image/ folder? not sure how its related tho.

Thanks
