www_root and admin_root in your environment.php file no longer contain /site/

Very many thanks for your patience and assistance. All working well.

Thanks for that. We are getting there. I added 'AllowOverride All' to the vhost entry for this site.

Pointing the web browser at [website] now results in total success. Thanks.
Pointing the web browser at [website/admin gives a 404 error BUT, at least it is a pretty Big Tree 404 (see below).

Page is headed by a black "Trees of All Sizes" banner with a functioning menu hamburger icon at the right hand side.
Page Not Found
404 Error

Hi again.

Things are slightly better after the re-install.
Pointing my browser at [website] shows "Index of /" and all the files and folders therein are shown below that title.

Initially, pointing my browser at [website]/admin showed a 404 message. I searched for the 'admin' folder and found it in the '/custom' folder.
In the 'environment.php' file, I set: $bigtree["config"]["admin_root"] = "http://[website]/custom/admin/";  but that also showed a 404 message.

I moved the 'admin' folder out of the '/custom' folder and placed it in the [website] root then amended the above line to  "http://[website]/admin/";
Pointing the browser at  [website]/admin now shows "Index of /admin" and all the files and folders therein are listed below that title.

I found that [website]/core/launch.php was not set to be executable. I set it to be executable but it made no difference.

If I point my browser at [website]/site I get the example site home page displayed but without any css etc., being picked up. Looking at the page source, this file expects to find the css at "http://[website]/site/css/site.css" but there is no such file at that location.

The possibility occurs to me that the installer for version 4.2.21 may be putting files and folders in the wrong places or has not correctly reflected the structure of the example site.

Any more ideas, please?

Yes, both correctly set. I'm going to wipe the installation (including database and vhosts settings and start all over again.

#5 Re: General » installation page = blank page » March 5, 2018 5:43am

Thanks for your comments. I confirmed that mod_rewrite is ON and I have amended the virtualhost entries. The result is that I now get a listing of all the files at the webroot when I point my browser at the site. When I attempt to get the admin site I get a 404 error. Copies of all (I hope) the relevant bits are shown below.

#6 Re: General » installation page = blank page » March 4, 2018 10:03am

I have just installed Big Tree on my local server but get a blank page on both the public-facing page and when trying to access the admin page
The apache2 access log entries are:
For public-facing page - '... [04/Mar/2018:13:45:45 +0000] "GET /index.php HTTP/1.1" 200 312 ...'
For the admin page - '... [04/Mar/2018:14:29:57 +0000] "GET /index.php/admin/ HTTP/1.1" 200 525  ...'

I set error reporting to 'all' and got the following result when trying to access both pages:
    Notice: Undefined index: bigtree_admin in /var/www/shrew3a/core/router.php on line 525
    Notice: Undefined index: extension_layout in /var/www/shrew3a/core/router.php on line 473
   Notice: Undefined variable: navid in /var/www/shrew3a/core/router.php on line 298

The htaccess file being used at the base url is:
    RewriteEngine On
    RewriteRule ^$ site/ [L]
    RewriteRule (.*) site/$1 [L]

The htaccess file being used within the /site/ folder is 2.8kB in size and starts with:
    <IfModule mod_deflate.c>
        <IfModule mod_setenvif.c>
            <IfModule mod_headers.c>

The site is being run with the following virtualhost setup:
    <VirtualHost *:80>
          ServerAdmin [blanked out]
          ServerName [blanked out]
          ServerAlias [blanked out]
          DocumentRoot /var/www/[blanked out]/site
      <Directory /var/www/[blanked out]/site>
        Options -Indexes +FollowSymLinks +MultiViews
        AllowOverride All
        Require all granted
      ErrorLog /var/www/[blanked out]/logs/error.log
      CustomLog /var/www/[blanked out]/logs/access.log combined

I am using php 7 and mysql server version 5.7.21

Any help will be gratefully received.
