This pashkivil is riddled with BS... She must have ticked someone (who is close to one of these rabbonim) the wrong way... the way they write that the there is an "Issur chumur" to go to her, without stating what the issur is, is just one of the many flaws in this pashkivil...
Without concrete proof, and at least some accurate details of what advise she gives that "these Rabbonim" don't approve of, i don't see sufficient enough proof to believe this information...
My gut feeling is that she gives advice that either she made up, or she gets from Rabbonim that are not sooo intensely chassidish... and they don't like that...
