I’m webmaster for a local community theatre site. We have a javascript code for tickets provided by “Vendini”. All was working fine until I installed NextGen and then suddenly the “Buy tickets now” button was replaced with part of the script code displaying.

Disabling NextGen restores the code to working order. Here are images of what it looks like with and without.
