Before you start make a backup of your boards files (but then you always do that don't you?) then download and unzip the attached. You will then find a folder called phpBB3 on your desktop. Within that folder there two folders (includes and styles) and one file (viewforum.php).Upload all of those to your boards root (where config.php is) and you will be asked if you want to overwrite those 6 files. Accept that and the files will upload.
Then purge your boards cache, either from the ACP or (if you can not access the acp) by removing the contents of the cache directory on your server, leaving just index.htm and .htaccess
NOTE If you do not use prosilver as your default style, you may have to edit up to four additional files. Open your default style and see if it contains any or all of the following, If any are present, edit them according to the instructions below otherwise the error will persist.
