(xcl 2.1.6a | pico 1.80a | linux | php 5.2.5 | MySQL5.0.67)

I installed pico as per instructions, but When trying to display content I get the following error (and a white screen):

Error [Xoops]: Smarty error: [in db:pico_main_viewcontent.html line 123]: syntax error: unrecognized tag 'd3comment' (Smarty_Compiler.class.php, line 590) in file class/smarty/Smarty.class.php line 1092

Any idea why this is happening?

Thanks in advance.
