Have you noticed anything not working properly or it's just error message?

no buttons are showing up at all

check your oxide/data/CustomButtons/CuiData.json, there's chance that it's empty, if not then upload the file here so I can have a look at it.

This is what is in that file. "Market": {

}

Also if i check PlayerData.json i get this error. Error: Parse error on line 27592: ...en": false }, ---------------------^ Expecting 'STRING', got 'EOF'.   And this is what it shows
  "76561198376589790": {
    "hidden": false
  },
  "76561199102087932": {
    "hidden": false
  },
  "76561198351712021": {
    "hidden": false
  },
  "76561198837903047": {
    "hidden": false
  },
  "76561198045284305": {
    "hidden": false
  },                                                               "THIS IS LINE 27592"
 

Ok i got it working again by changing that line to.
    "hidden": false
  },
  "76561198045284305": {
    "hidden": false
  },
  "76561198251161206": {
    "hidden": false
  }
}

it put in the console this when i made that change and reloaded the plugin.
