Power Bi reports Background color changed when Published

Hi Anonymous,

>> Is there anything else I need to do to remove the theme file?

You can click on change theme option and choose use default theme to restore default style.

>>Also, Does it matter the location of the .json file? Few days back I moved the file to different folder. Is that the cause of it?

Delete theme file not effect enabled theme effect, when you import theme file, it will also import json setting to power bi report.

For background color issue, I think it should related to below bold part:

{"name":"20171123_AKra",
"background":"#FFFFFF","foreground":"#124191","tableAccent":"#124191",
"dataColors":["#124191","#00C9FF","#001135","#FF3154","#E61E1E","#E6AA1E","#FFFB00","#4BDD33","#82BE1E","#641464",
"#EDF2F5","#BEC8D2","#98A2AE","#4D5766","#273142"],

"visualStyles":
{"*":{"*":{"*":[{"fontSize":10,"fontFamily":"Arial","color":{"solid":{"color":"#124191"}}}],
"general":[{"responsive":true}]}},

"card":{"*":{"labels":[{"fontSize":28}],"categoryLabels":[{"fontSize":14}]}}
}}

Please use below code to replace original one and test to re-publish:

{
   "name":"20171123_AKra",
   "background":"#FFFFFF",
   "dataColors":[
      "#124191",
      "#00C9FF",
      "#001135",
      "#FF3154",
      "#E61E1E",
      "#E6AA1E",
      "#FFFB00",
      "#4BDD33",
      "#82BE1E",
      "#641464",
      "#EDF2F5",
      "#BEC8D2",
      "#98A2AE",
      "#4D5766",
      "#273142"
   ],
   "visualStyles":{
      "*":{
         "*":{
            "*":[
               {
                  "fontSize":10,
                  "fontFamily":"Arial" 
               }
            ],
            "general":[
               {
                  "responsive":true
               }
            ]
         }
      },
      "card":{
         "*":{
            "labels":[
               {
                  "fontSize":28
               }
            ],
            "categoryLabels":[
               {
                  "fontSize":14
               }
            ]
         }
      }
   }
}
