<!--more--> is also filtered by htmlspecialchars

[fightbulc]

When one adds the <!--more--> tag into his post Wordpress transforms this tag as well with htmlspecialchars which leads to the mistake that "get_the_content()" doesnt recognize the tag anymore. By this the excerpt function isnt given anymore.

Easy adjustment can be done in "post-template.php" line 107 - 111.

I checked into this and if you manually type <!--more--> it does do as you say. However if you click the more button it works perfectly fine.

If you want to enter the more tag manually, You need to enter it in the HTML view rather than the Visual view.

Yes, the visual view figures you wanted to actually display a < (i.e. &lt;) and not use it for code. It is a what-you-see-is-what-you-get editor after all. ;)
