Hi. Given my poor access to the internet I am setting up a USB server so I can work on developing the structure of the site. The server is XAMPP from https://www.apachefriends.org/index.html
php 7.2.4
The purpose here is not just to get help but to provide a step by step for anyone else interested
I'm using a 2GB USB with NTFS formatting.

1. I transferred my site {version 6.9.5 with a modified simple_zen skin ~ which you can see at http://calstock.org.uk) to the local [htdocs] with the following issues.
2. Using the phpMyAdmin I created a database using the same name, user name and password as my online site.
3. The install uses MariaDB rather than my online MySQL which seems fine. http://forums.b2evolution.net/mariadb-mysql
4. I had to modify [\xampp\apache\conf\extra\httdp-default.conf] and change the Timeout from 300 to 900 as the transfer of the database contents kept being cropped with the timeout warning.

OK All good so far now I have a few error messages to deal with one at a time.

1. Deprecated: __autoload() is deprecated, use spl_autoload_register() instead in H:\xampp\htdocs\calstock.org.uk\inc_core_class_loader.funcs.php on line 55

So the problem here is the file mentioned looks as though it should have dealt with that

if( function_exists('spl_autoload_register') )
{
	// spl_autoload_register( 'var_dump' );
	spl_autoload_register( 'evocms_autoload_class' );
}
else
{
	// PHP<5.1.2: Use the fallback method.
	function __autoload( $classname )
	{
		return evocms_autoload_class($classname);
	}
}

so if anyone has any ideas while I look into it, that would be appreciated.
UPDATE
Should exist in (PHP 5 >= 5.1.0, PHP 7) ::: So what? the function couldn't be found so ( autoload) was invoked??
autoload is depricated since php7.2.4 https://secure.php.net/manual/en/function.autoload.php
OK by inserting an echo I see the code above is working. I now think the 'output' is more a 'notification' that may not have appeared except for the following

'warning and 3 'error'

warning and error :: OK a missing file sorted these. Somehow I have a [/skins/_toolbar.inc.php] in my online site but wasn't in my ftp transfer.
Still get the notification about (spl_autoload_register) which I can probably suppress :)

So finally the formating and stuff :: probably as I have some http URL's and
of course the baseline URL will be wrong. SORTED $baseurl = 'http://localhost/calstock.org.uk/';

So seems almost sorted. Recognisable site with anomalies. Will detail them if I resolve them and they seem relevant

Thanks for reading this.
