Hi,

I currently have the following error in the Wizard:

mwe-upwiz-source-ownwork-assert-cc-by-sa-3.0-ro: Parse error at
position 263 in input: Eu, $2, titularul drepturilor de autor ale
{{PLURAL:$1|acestei lucrări|acestor lucrări}}, ofer oricui dreptul
irevocabil de a folosi {{PLURAL:$1|această lucrare|aceste lucrări}}
sub licența Creative Commons
Atribuire-Distribuire-în-condiții-identice 3.0 România ([ $3 textul
juridic])

and I just can't figure out what the error is (position 263 seems to
be the open round parenthesis). Can someone help?

Thanks,
  Strainu
