Incompatibility with CF7 4.6.1

After updating your plugin to 0.5.6 CF7 send the e-mail and after the spinning arrow shows and it stops, infact the redirecting fails and the page freezes.

I tried a debug with Chrome and i obtained the follow error:

“<br />
<b>Warning</b>: Illegal string offset ‘file_tags’ in <b>/web/htdocs/www.noiagricoltori.it/home/wp-content/plugins/send-pdf-for-contact-form-7/classes/send-pdf.php</b> on line <b>266</b><br />
<br />

{“mailSent”:true,”into”:”#wpcf7-f28925-p28922-o1″,”captcha”:null,”message”:”Grazie per il tuo messaggio. \u00c8 stato inviato.”,”onSentOk”:[“location = ‘\/tc-home\/’;”]}”

I hope this is a valid help for solution to the problem.

Thanks in advance and congratulation for the plugin.

P.S. – for the moment i unistalled it and all is ok.
