warning

ciao scusatemi ma non capisco perchè nella parte amministrazione mi arriva questo warning:
Warning: Missing argument 2 for l(), called in /Users/leo/Sites/acquia-drupal7.19/sites/all/modules/contrib/ds/modules/ds_format/ds_format.module(66) : eval()'d code on line 10 and defined in l() (linea 2413 di /Users/leo/Sites/acquia-drupal7.19/includes/common.inc).

da quanto capisco io non gli arriva questo valore l() nel ds_format.module (cos'è sto 66? un nodo?)  e sti : eval()'d code (?booh?) nella linea 10
che però è definito nel l() della linea 2413 nel common.inc   ...giusto?

e io cosa dovrei fare? ho solo installato i moduli! cioè nel senso che non sono un programmatore per cui non capisco se basta cancellare qualche riga del codice o  fare altro o lasciare così che tanto il sistema funziona....
allego anche i due rispettivo blocchi di codice, magari voi che ci capite qualcosa forse riuscite anche a faremi capire cosa vuol dire sta roba... vi anticipo che sarà dura ;) ma vi ringrazio cmq!
