Parse Error: syntax error del file functions.php

[ragnodiquartiere]

Buona sera, credo di aver messo mano dove non dovevo!

Ho avuto la brillante idea di vedere se potevo aggiungere la funzione di inserire tag all'interno dei miei articoli in modo che quando qualcuno ci clicchi sopra venga rimandato a tutti quei tag (dovevo scrivere una serie di articoli tutti connessi tra di loro, ma non dovevano appartenere ad una determinata categoria quindi stavo pensando di sfruttare gli hashtag, creandone uno per averli tutti, sia sul blog che sui social).

Mi sono imbattuto in una guida dove diceva semplicemente di aggiungere la funzionalità nell'editor del file functions.php.

Ebbene, una volta fatto mi è comparso un errore di sintassi alla linea 279.

Ho prontamente rimosso il codice ma il problema ora persiste! Il problema è che, analizzando l'intero codice con un editor di testo php, le linee totali sono solo 277. Quindi questo errore dov'è?

Purtroppo a livello codice ne capisco ben poco, cercando su internet dovrebbe essere dovuto semplicemente da una mancanza di ";" oppure "\" ma, ripeto, non c'è la linea che mi viene indicata.

Scusate il doppio post ma non entrava tutto in unico post causa mancanza di caratteri.

Continua.

Non riesco ad individuare l'errore. Metti provvisoriamente un tema standard così riattivi il sito. Poi cerchi di risolvere il problema col tuo tema attuale (oppure disinstalli e reinstalli il tema, così ripristini il function.php)

[ragnodiquartiere]

Grazie per la risposta darkwolf. Avevo pensato a reinstallare o reintrodurre il file functions.php, ma non posso più accedere al pannello di controllo.

Ti riferisci all'installazione con filezilla eventualmente?

[darkwolf]

Se hai accesso ftp è un'idea. In caso di alterblog, invece, vai di ripristino.

[ragnodiquartiere]

Perfetto ci sono riuscito. Non credevo fosse fattibile perchè avevo considerato solamente il pannello Wordpress e non quello Altervista. Grazie mille per la dritta e buona serata! :-)
