I've been getting the following error
Warning: Division by zero in /home/xxxxx/public_html/wp-content/plugins/tumblr-widget-for-wordpress/tumblr-widget.php on line 295 ...
Tried to fix it but didn't seem to work. I found that line and it reads
$old_width = $matches;
$old_height = $matches;
$new_height = $old_height; (this is line 295)
The only thing I could see was that maybe it needed a number after old height similar to the others. So I tried that and it didnt work.
I've deactivated it and deleted it while I wait to see what can be done to fix it.
