Hi Ricardo Martins Sangion,

I am really sorry for the delay of this reply as it is a weekend for us here.

Can you provide us with your Joomla backend and FTP access so we can help you check on this ?

*You can put the information in the optional information field below(SITE DETAILS). Don't worry about privacy. Only Support team can view the information.

After several changes from one theme to another, it finally got to work.
Feedback is that, after the update, the theme went to "default", even though the configuration was set to Simplistic.

I have another site and it's working, so maybe it's some conflict with the current theme (iReview3)

I have added the site information for you

Hello Ricardo Martins Sangion,

For the toolbar not showing issues you can insert css codes below into /templates/ireview3/css/custom.css

div#fd.eb .eb-navbar-collapse {

    visibility: visible;

}
