Ciao a tutti,
sono nuovo e vi scrivo per un problema con il captcha in un sito che sto facendo, in pratica non si vede dandomi l'errore
[font=times new roman][size=medium]Parse error: syntax error, unexpected T_STRING in/web/htdocs/www.musumecichisariarchitetti.it/home/plugins/captcha/recaptcha/recaptcha.php on line 71[/size][/font]
[font=verdana][size=1em] ed in più mi ha modificato il template della pagina contatti dopo aver seguito le istruzioni dell'articolo
http://www.joomla.it/articoli-community-16-e-17-tab/7315-joomla-25-plugin-recaptcha-e-sparito.html.[/size][/font][size=78%]
Ho letto altre discussioni su questo argomento sempre in questo forum ma a parte le modifiche già apportate non ho trovato altre soluzioni, ultimo tentativo che ho eseguito è stato copiare l'intero codice di un altro file recaptcha pubblicato sempre in questo forum ma come detto prima mi dà questo errore.
Joomla è la versione 2.5.4, che purtroppo sono obbligato ad utilizzare perchè compatibile col template scelto, quindi non posso aggiornarlo perchè versioni superiori non lo supportano.
Capisco dall'errore che il problema dovrebbe essere alla linea 71, ma purtroppo non capisco qual'è l'errore anche andando a guardare il file, anche perchè col php sono all'inizio.
Pubblico il file recaptcha.php:
