[Plugin: Web Invoice] Problem with TinyMCE after enabling this Plugin

I am also having this issue. I have isolated it to the Web Invoice plugin.

I am looking into modifying the plugin to only load the Javascript it required when I am on a Web Invoice page. This is a very annoying issue.

Okay, I have found a work around solution to the problem.

It is definitely javascript interference.

I modified the web-invoice.php file to only load it’s required javascript on it’s own pages instead of on every admin page as described in the article linked below.
