Hello

Admittedly I am unable to replicate this issue, however, I have just updated to the latest Joomla version and rebuilt the demo installer for this template which should hopefully resolve this issue. To obtain simply re-download from your template downloads.

Ciaran

Hi Ciaran, I downloaded the file as you said and tried the installation; unfortunately the problem remains. Do you have any advice for me.
Thank you

Hello

May I suggest sending temporary administration access to your Joomla installation server to info@joomla51.com and we will examine this issue further. For our reference please paste a link to this post in your email.

Hi Ciaran,
I cannot complete the installation process and therefore I do not have access to the administrative side. I can provide FTP access data to the hosting space and access data to the mysql database. I'm waiting for a response thanks

I'm not great in Italian, but from the error message you got, you seem to have a problem with your browser. Maybe you have an adblocker active or too strict security restrictions. I'd suggest using a different browser for this activity.

Hi Rolf
Thank's for your answer. I already checked; the browser has no restrictions.
I don't know what to do, Ciaran do you have any suggestions?

Hello

Could I ask you to paste the text of error? Unfortunately, my Italian is non-existent
