Uploading .GIF 3.8.7

[MatthewE]

I'm not sure if this is just me but if you upload a GIF with an underscore (_) in the name like a user did, it comes up with a database error, not sure why although I'm not sure if this is just .GIF or all image types,
Any ideas?

Try disabling your modifications/plugins and see if you still have this problem.
Note: To temporarily disable the plugin system, edit includes/config.php and add this line right under <?php

define('DISABLE_HOOKS', true);
