You just need to enable syntax highlighting in the EasyMDE settings.

The editor toolbar looks different here because I’m testing a new editor that will be used for the Pro version. However, you have the same code block with the same functionality in EasyMDE.
I enable syntax highlighting but it sees the code as text


before to try this version, I wanted to deactivate the installed version
but I can't, It's grayed out.Is it normal ?
Yes, it’s completely normal that you can’t disable EasyMDE. This plugin is essential for creating messages.
However, it’s not a problem — just replace the entire plugin folder. With this version, you’ll be able to enable or disable it, although disabling it is not recommended.
This EasyMde version is the same 2.3.1 , and the result is the same no color

Do you have a way to clear the cache?
You can force your browser to refresh with Ctrl+R, or use Flatboard’s dashboard maintenance, or manually delete storage/cache.
I just activated EasyMDE here.
I clear the cache, browser changed firefox/chrome no results.Can someone try it on the free flatboard edition? Does it work? Pehaps that I have'nt the good right on my server?

Please check if there are any errors in your browser console.
Is it a 403 error when loading a JS/CSS resource, or a JavaScript error?
Could you provide the URL of your forum so I can investigate the issue?
To troubleshoot the syntax highlighting issue, follow these steps:
Check Browser Console for Errors
- Open your browser's developer tools (F12 or Ctrl+Shift+I).
- Go to the Console tab and reload the page.
- Look for any 403 errors (forbidden access) or JavaScript errors related to loading resources.
Verify File Permissions on Your Server
- Ensure your server has the correct permissions to access the EasyMDE plugin files.
- Check if the files are readable by the web server (e.g.,
chmod 644for files,chmod 755for directories).
Test on a Fresh Flatboard Installation
- Download the latest version of Flatboard and set up a test forum.
- Enable EasyMDE and check if syntax highlighting works there.
- If it works, the issue may be with your current setup or server configuration.
Compare with the Official Flatboard Forum
- Visit Flatboard's official forum and check if syntax highlighting works there.
- If it does, your issue may be specific to your server or configuration.
Provide the Forum URL for Further Investigation
- Share the URL of your forum so that others can inspect the issue directly.
If the problem persists, consider sharing the console errors or any relevant server logs for further assistance.
Hello,
You must specify the language type (PHP, Java, etc.) at the beginning of the code.
I didn't know, sorry for the inconvenience

echo "Hello World";
const x = 42;
This is precisely the purpose of a syntax highlighting plugin in an editor: to recognize the language being used and apply the corresponding formatting rules. When the language is not specified in a code block, the plugin treats it as plain text. However, as soon as the appropriate language is indicated, the syntax highlighting adjusts automatically, greatly improving readability and presentation.
The key is just to know it 😉
