How-to: Collecting PhpStorm/WebStorm Debug Logs

The instructions below refer to PhpStorm, but the steps for WebStorm are the same.

To enable debug logging, you need to:

1. Open Help | Diagnostic Tools | Debug Log Settings...

2. Add the following lines:

• Issues with PHP: #com.jetbrains.php
• Issues with FTP/FTPS/SFTP deployment/synchronization: #com.jetbrains.plugins.webDeployment
• Issues with SSH/SFTP: #com.intellij.ssh

3. Click OK

4. Reproduce the problem.

5. Log files can be found at:

• In PhpStorm/WebStorm:
  • Help | Show Log in Explorer/Files/Navigator/Finder
  • Help | Collect Logs and Diagnostic Data
    

• Manually (~ stands for the user home directory and XX for the number of the version):
  • Windows: %USERPROFILE%\AppData\Local\JetBrains\PhpStormXXXX.Y\log
  • Linux: ~/.cache/JetBrains/PhpStormXXXX.Y/log
  • macOS: ~/Library/Logs/JetBrains/PhpStormXXXX.Y

More information about the directories used by IDEs can be found here. 

The latest log file is named idea.log, older files names end with a number, i.e. idea.log.1, idea.log.2, etc. In most cases, you need only the latest one.
