I'm using the following plugin to make BBCode works in Wordpress. Plugin is no longer supported, so I need to ask here for help...
Plugin changes BBCode to HTML code by defined shortcodes. Everything worked fine until upgrade to Wordpress 4.4.
Some of them stopped working, like [url], [color] - normal plain text is displayed, but others still work, like [b] still makes text <strong> properly.
I have searched through functions.php and post.php (difference between previous, 4.3.1 version and current 4.4), to find a clue what could happen, but I didn't find a solution.
Does anyone know how to fix it?
