title: How to fix plotly offline error?
body: <p>I followed <a href="https://stackoverflow.com/questions/37745917/using-plotly-without-online-plotly-account">Using plotly without online plotly account</a> and did the following code at the beginning of a notebook:</p>
  
  <pre><code>from plotly.offline import download_plotlyjs, init_notebook_mode, plot, iplot
  init_notebook_mode(connected=True)
  
  import plotly.plotly as py
  import plotly.graph_objs as go
  from plotly.graph_objs import *
  import cufflinks as cf
  </code></pre>
  
  <p>But I still have the error:</p>
  
  <p><code>PlotlyRequestError: Account limit reached: Your account is limited to creating 25 charts. To continue, you can override or delete existing charts or you can upgrade your account at: https://plot.ly/products/cloud</code></p>
