When I preview a new post that contains the "pre" tag, WP-Sentinel is triggered and blocks the previewing page and warns of HTML code injection attack. The message given in WP-Sentinel's alarm report is:
- Variable content of the POST method triggered the filter 'script or html injection' for the content '<pre>test</pre>'.
I'm not sure why this normal activity of previewing is blocked by the plugin. Sounds like a bug to me.
