Hi Deriv Community! 
If you see any of the error messages below in your Journal section, this means that the mandatory blocks in your DBot workspace are either missing or disabled.
Error messages:
- One or more mandatory blocks are disabled from your workspace. Please enable the required block(s) and then try again.
- One or more mandatory blocks are missing from your workspace. Please add the required block(s) and then try again.
There are 4 Mandatory Blocks in the DBot workspace. The first 2 Blocks, Trade Parameter and Purchase Condition are the most important Block for the bot to start executing a trade. Hence, you would need to ensure that the blocks are not disabled or missing
By default, all the blocks will be populated accordingly on the workspace when you launch the DBot platform.
1. Mandatory Blocks Disable
If you see the error message above on your Journal section in DBot, the Mandatory Block or the Mandatory Parameter might be disabled, or the Mandatory Parameter is disabled due to not being placed accordingly in the Mandatory Block.
For this case, you can enable the Mandatory Block or the Mandatory Parameter by Right Click 
Enable Block or inserting the Mandatory Parameter accordingly in the Mandatory Block.
2. Mandatory Block Missing
If you see the error message above on your Journal section in DBot, the Mandatory block or Mandatory parameter is missing from the Workspace.
To overcome this, you may insert the Mandatory Block in the Workspace or insert Mandatory Parameter accordingly in the Mandatory Block.
