Hello,
The warning means that the first parameter is an array instead of a string. 
You can try to dump the value of this variable to see what it looks like: 
{$_smarty_tpl->tpl_vars['position']->value|dump}
or on PS 1.6
{$_smarty_tpl->tpl_vars['position']->value|var_dump}
Also, these are cache files, and you probably need to solve the issue in the original files, so try to turn off and delete the smarty cache and check the errors in the original, not cached, tpl files.
I hope that I could help.
Have a nice day, Leo.
