RISOLTO non riesco più ad accedere come admin

[forbiddden]

la schermata di accesso accetta user e pass (ho pure resettato dal cPanel X la pass) ma il risultato è che ritorna la stessa schermata di richiesta pass senza alcun errore.
In /public_html/administrator ho trovato un file error log insieme a tre index.php (index index2 index3) non ricordo se tre ce ne sono sempre stati.
Posto il contenuto del error log

sembra c'entri improvvisamente phocafont che ho installato e attivato ma non so se e come intervenire per disattivarlo semmai è lui il responsabile senza poter entrare nel pannello di controllo.
grazie per la cortese attenzione

[jeckodevelopment]

ciao Forbidden,
se hai un backup precedente all'installazione "Incriminata" ti converrebbe ripristinare quello.

[forbiddden]

grazie per il consiglio.
non ho alcun backup precedente a phocafont, al suo plugin ed alla modifica dei due files (/administrator/components/com_phocafontconfig.xml e /administrator/components/com_phocafontconfig.xml) per l'uso di più fonts.
ma possibile che usare un semplice componente per altro molto diffuso e il suo plugin rendano il css completamente inservibile e l'unica soluzione è reinstallare tutto???

[jeckodevelopment]

generalmente, soprattutto quando le estensioni sono molto diffuse, non creano conflitti di questo tipo.
E' strano che non ti faccia accedere in amministrazione.
Prova a svuotare la cache del tuo browser innanzitutto (parla di non riuscire ad inviare cookie)

[forbiddden]

Trovato il problema!!! 

Partendo dal presupposto che il log parlava di Phoca Font ho provato ad accedere al database nella cartella plugins (jos_plugins) ed a modificare il valore uno con zero nella colonna plublished per disattivarlo (non so se cosi' funziona, ma questa era la mia intenzione). Risultato: accesso sbloccato ed il pannello di controllo e' tornato a funzionare!!!
Abbastanza paradossale però 

[jeckodevelopment]

ottimo, hai disattivato il plugin e funziona.
Se il plugin ti è necessario, prova a partire dalla sua config. di default e magari adattane il setup in maniera graduale per vedere dove è il problema.
