After using DMS for many years with no problem, upgrading as things became available etc, I started getting so much spam that it started to slow down my ISP's server!!
Predominately from 2 IPs, one in China and one in Russia.
I have a good relationship with my ISP and they offer a great service but as a result of the attacks they have put in a htaccess block on that guest book page and asked me to come up with a solution.
Last w/e they upgraded to PHP Version : 5.2.17-0.dotdeb.0
PHP Safe Mode : Off
PHP Allow URL fopen : Off
I downloaded the anti-spam plug-in and set about moving the guest book to a new page.
On opening the new page I received a stream of Error messages commencing with
WARNING function.fopen URL file access is disabled in the server configuration in ........../dmsguestbook.php on line 691.
So many error messages the browser crashed!
I tried in the 2012 theme with all other plug-ins disabled with the same result.
I tried some stuff that I found in support forums, not really understanding what I was doing, but still no joy.
