Ah! I guess i shall have to find a new set of templates for that site so.
I believe those dp_yellow templates were installed in 2006/7, the old desktop their folder was on, went into recycling around 8yrs ago.
I cant remember who made that set and cant find them on the templates list here, even googled "dp_yellow" but nothing!
Update:
Discovered the site had been hacked by something called "Masrer". Now eliminated!
The dp_yellow template was by Decopix, buut they no longer exist
http://decopix.de/The chances of someone having a copy of that template is slim, and i just cannot find a similar one to replace it!
