Analysing limits

  1. When your account has reached any limit, you can find this here. If you have reached a limit, it is normal to see a high number of times when the limit was reached. This is because PHP scripts usually continue to run and quickly hit the same limit again and again.
  2. Click on Details. Loading the graph may take some time.
  3. In table 1 you can view the legend for the table with all limits. In the interactive graphs you can find the exact times when the limits were hit.
