white page installing add-ons


Active member
I upgraded to 1.1.0 several weeks ago and today i tried to install a new add-on (i didn't install any add-ons months ago).

When i uploaded xml, i only show a white-page with the next URL:

www.domain.com/admin.php?add-ons/install (My forum is on root)

I tried to enable errors via library/config.php page and disable all add-ons, but still got same white page.

Server xenforo error log dont show nothing.

What can i do?

I tried now 2 add-ons and none works. Also tried xenforo file check and said all is ok. I can uninstall add-ons, but not install it.

Before i had no problems with add-ons.

A blank page is often a suppressed error. Try adding this line to your library/config.php file:

ini_set('display_errors', true);
Or add this to a .htaccess file on your server (only works on Apache servers):

php_value display_errors 1
That may reveal an error message on the blank page.
