GSgallery 2.0 - Simple Image Gallery Plugin (Square It)

[WebFXWorld]

Installed SIG 2.5(beta), but when I try to save "Photo Gallery" page with SIG code, I get the following errors:

(Deprecated: Function ereg() is deprecated in C:\xampp\htdocs\trina\admin\changedata.php on line 23)

Can you help, please?
