Special symbols are replaced by its code when entering post editor

Hi there,

I tried replicating the issue as you described on my test website using some boilerplate HTML code but could not reproduce the problem.

The code was rendered correctly, including the < & > symbols both times, i.e., when I first created the post and then edited & saved the post.

To help us understand, please share the code with which you are having the issue.

Which version of WordPress & SyntaxHighlighter Evolved plugin is installed on your website?

Are you using the Block Editor or the Classic Editor on your site?

Hello,

I am using the Block Editor. SyntaxHighlighter Evolved Version 3.6.1, WP Version 5.9.2.

Lang I am using is “csharp”.

Here is the code example

       drawCommands->drawCommands[0].visibleOffset = 0;
        drawCommands->drawCommands[0].visibleCount = _instancesCount;
        drawCommands->drawCommands[0].batchID = _batchID;
        drawCommands->drawCommands[0].materialID = _materialID;
        drawCommands->drawCommands[0].meshID = _meshID;
        drawCommands->drawCommands[0].submeshIndex = 0;
        drawCommands->drawCommands[0].splitVisibilityMask = 0xff;
        drawCommands->drawCommands[0].flags = 0;
        drawCommands->drawCommands[0].sortingPosition = 0;

It doesn’t happen every time, but still very often.
Here is how it is rendered on a preview page:

How it looks in the editor:

And that’s a revision history example:

It keeps adding more and more codes. And usually I see 2 revisions saved simultaneously when I open the post to edit.

Hi again,

Thanks for getting back to us! I checked the issue on my test website, but I could not replicate the problem.

Here is a screencast of the test https://d.pr/i/YPQPl5

It’s possible that there might be a conflict with one of your current plugins or your theme.

Try disabling all of your plugins except SyntaxHighlighter Evolved. Then try testing again to see if the issue persists. If that resolves your issue, you can find what was causing it by enabling each plugin one by one while continuing to test.

If that doesn’t help, you can also try switching to the Twenty Twenty theme via Appearance > Themes, and test again. If the issue is resolved then you know it’s a problem with the theme, and you’ll need to contact the theme author for further assistance.

Let us know how it goes.
