Hello/Hi/Greetings,

I wanted to upload some photos to my gallery, and I'm getting this error message :

Deprecated: __autoload() is deprecated, use spl_autoload_register() instead in /customers/a/7/5/diehardagnetha.com/httpd.www/gallery/plugins/user_tags/include/autoload.inc.php on line 31 Warning: Cannot modify header information - headers already sent by (output started at /customers/a/7/5/diehardagnetha.com/httpd.www/gallery/plugins/user_tags/include/autoload.inc.php:31) in /customers/a/7/5/diehardagnetha.com/httpd.www/gallery/include/page_header.php on line 101

I can'ty enter keywords anymore ; if I open a picture (edit), there are no keywords present. In the gallery I can see the keywords beneath the picture....

I have another site (exactly the same, but with other content) and that one doesn't produce an error message.

I have added a screenshot of my site with the error (DHA) and a screenshot of the site that runs normally (EGP).
