$$D_mu.=partial_mu+iqA_mu$$
$(D_muD^mu+m^2)phi(x)=0$
Expliciting:
$(partial^mupartial_mu+iqpartial^muA_mu+iqA^mupartial_mu-q^2A^2+m^2)phi(x)=0$
Setting Lorenz gauge: $partial_muA^mu=0$
I do not understand why I get:
$(square +2iqA^mupartial_mu-q^2A^2+m^2)phi(x)=0$
Instead of:
$(square +iqA^mupartial_mu-q^2A^2+m^2)phi(x)=0$
