Blank page instead of an ecard

[arivera]

Hello,

I'm sorry if this has been solved previously but I couldn't find an answer to this in previous posts. I can send and receive ecards from Coppermine with no problems. I can see the ecards on my email but if I click on the "Alternate link if the e-card does not display correctly" link, all I get is a blank page.

This happens if I'm logged as a regular user, if I'm logged in as admin, I get this message:
Fatal error: Call to undefined function: html_entity_decode() in /var/www/html/gallery/displayecard.php on line 44

How can I fix this?

Thanks in advance!
