I have done a search in regards to fatal error during installation for SS 2.2.1 on Web Drive shared PHP5 hosting.

It went alright except it gets to this error: Fatal error Cannot redeclare class Form ...

I cannot find any solution at all! Anyone care to give help on how to install SS on Web Drive?

Sorry to hear you're having installation woes. It's always tricky given the variance in how webfarms set up their servers.

So, I see a bunch of advice, including;

Which point to
(a) Increasing memory limit beyond 32MB

(b) Manually setting the .htaccess file's rewrite rule;
(-)RewriteRule .* sapphire/main.php?url=%1&%{QUERY_STRING} [L]
(+)RewriteRule .* /<<subfolder>>/sapphire/main.php?url=%1&%{QUERY_STRING} [L]

c) Noting that WebDrive uses Mod Vhost Alias:
VirtualDocumentRoot /home/httpd/vhlinks/%0/
"I assume the VirtualDocumentRoot is causing the problem for SilverStripe." says a poster.

(d) A developer here sorted the issue by changing the core/ManifestBuilder.php line 39
// Config manifest
// $baseDir = dirname($_SERVER['SCRIPT_FILENAME']) . "/..";
$baseDir = '/path/to/files';

If you do get it solved (item d could be your savior) we would love to know precisely what you needed to do so that we can patch the software with a fix. Until someone does this, others will stub their toe on webdrive which is a shame.

Finally, do note that "cannot redeclare" implies it is including the same file or code twice, so I'd hope you didn't accidently unzip SilverStripe twice and that its somehow embedded in itself.

it was virgin SS installation so couldn't possibly be any duplication.

I will step through the suggestion and hopefully I could be of help to find the cause and the workaround/solution as to SS on WebDrive.

Thanks so much with a reply, at least it allows me to start my troubleshooting.

Okay, point (A), I think it is fixed by your latest SS 2.2.1 code, so it is automatically set to 32M (as my phpinfo reported the server setting is at 20M)

I've added "php_flag allow_call_time_pass_reference on" on .htaccess so I get all green for installation.

point (B), if i add that line in into .htaccess before the installation, I get error 500. If I remove it, I get the installation screen.

point (C), I do not understand what you suggest there, it doesn't get me far.

point (D), no such line at core/ManifestBuilder.php line 39. However a search for "dirname($_SERVER['SCRIPT_FILENAME'])" found it at line 85 and 382.

So I'm back to square one that it doesn't help me with the solution from 2007. I need a solution that is for SS 2.2.1.

Please help again.

Hmm. Scanning through my email I see this comment, as well, from Nicolaas... maybe he can shed some light?

Change .htaccess

RewriteRule .* sapphire/main.php?url=%1&%{QUERY_STRING} [L]
RewriteRule .* /{QUERY_STRING} [L]

This is what I had in my .htaccess file with the site running in PREVIEW mode:

RewriteBase /
php_value memory_limit 64m
php_value allow_call_time_pass_reference 1
RewriteEngine On

RewriteCond %{REQUEST_URI} !(\.gif)|(\.jpg)|(\.png)|(\.css)|(\.js)|(\.php)$

RewriteCond %{REQUEST_URI} ^(.*)$
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule .* /{QUERY_STRING} [L]

Now... do I add those into the .htaccess before I perform the installation? or after? Because the installation didn't seem to complete, and no database created, so when or how do I know when to add those lines into .htaccess?

I would try before. Sorry, I cant be of more help here. It is usually easier to contact the ISP - they can help you.
