Oh My Posh Update Troubles: Theme Gone Missing?

Oh My Posh is a fantastic tool for customizing your terminal prompt, giving you a sleek and informative interface. It's highly customizable, allowing you to display exactly the information you need, and it integrates seamlessly with various shells, including PowerShell. However, like any software, updates can sometimes introduce issues. In this case, a recent update seems to have caused the theme to disappear for some users. If you've recently updated Oh My Posh and are now staring at a prompt that says "CONFIG ERROR", you're not alone. This guide will walk you through the problem and offer potential solutions.

The Problem: Where Did My Theme Go?

The core issue seems to stem from a change in how Oh My Posh locates its themes after an update. The user's prompt shows a CONFIG ERROR message. The environment variable POSH_THEMES_PATH is pointing to the correct themes directory, which is supposed to be located at C:\Users\{yourusername}\AppData\Local\Programs\oh-my-posh\themes. However, when checking the file system, the "Programs" directory under AppData\Local is missing. This likely means that the update process didn't place the theme files where Oh My Posh expects them to be, leading to the error. Because of this, the user is unable to identify their current theme within their configuration, or within their init.ps1 file.

Troubleshooting Steps

When a theme is not working correctly, you should go through these steps. First, confirm the version of Oh My Posh. Winget is used by the user, and this method is straightforward. Open PowerShell and run the command oh-my-posh --version. The output will display the version number. This helps determine whether the update was successful, as well as if future steps have resolved the error. Next, check if the theme files are present, or missing. Even though the POSH_THEMES_PATH variable points to the correct location, it is missing the themes directory. Because of this, it can also lead to the issue. Go to the default theme directory, and see if it is populated. Now you can rule out a theme-related issue. If the theme files are missing, it confirms the update messed up file locations, as mentioned before.

Possible Solutions and Workarounds

Here are some steps you can take to try and fix the issue:

  1. Reinstall Oh My Posh: The simplest approach is often the best. Try uninstalling Oh My Posh using winget uninstall JanDeDobbeleer.OhMyPosh in PowerShell and then reinstalling it with winget install JanDeDobbeleer.OhMyPosh. This should ensure that all necessary files, including the themes, are placed in the correct locations.
  2. Manually Check Theme Directory: If the reinstallation doesn't work, manually check the C:\Users\{yourusername}\AppData\Local\Programs\oh-my-posh\themes directory. If the themes are missing, you can try to copy them from another installation, a backup, or from the Oh My Posh GitHub repository.
  3. Verify Theme Configuration: Even if the themes are present, double-check your Oh My Posh configuration file (usually jandedobbeleer.omp.json or similar) to ensure the theme setting is pointing to the correct theme file. The config file tells Oh My Posh which theme to load. Verify that the file exists in the themes directory. Open up your config file in a text editor like VS Code and examine its contents. Look for a line that specifies the theme, such as `
