Can't install

[Cassandra Simons]

I am new to Joomla. I have installed Joomla and then I try and install the virtuemart package 'com_virtuemart 2.0.18a.tar.gz' and it doesn't work and goes to a blank page on Firefox. It has this message when I try it on Chrome:

The website encountered an error while retrieving http://www.peregrineweb.co.nz/joomla/administrator/index.php?option=com_installer&view=install. It may be down for maintenance or configured incorrectly.
Here are some suggestions:
Reload this webpage later.
HTTP Error 500 (Internal Server Error): An unexpected condition was encountered while the server was attempting to fulfill the request.

I have uninstalled Joomla and reinstalled it and then tried to install Virtuemart in the extension manager again and it still does the same thing.

Having the same problem with a new site.  Just goes to a blank page. I don't have another browser to try it on.  Is this a common issue?

Did you unzip (untar) the package once? See here: http://dev.virtuemart.net/projects/virtuemart/wiki/Installation_of_VirtueMart_2_with_provided_packages

[Cassandra Simons]

Yes. I have the 'com_virtuemart.2.0.18a.tar.gz' and 'com_virtuemart.2.0.18a_ext_aio.tar.gz' packages.

So, should I just abandon Joomla? The only reason I installed it is to install VirtueMart, and it doesn't work!

You may not have sufficient PHP resources on the server. See http://forum.virtuemart.net/index.php?topic=102045.msg339125#msg339125

Alternatively you could have a .htaccess file causing problems.

I also have this problem there is no way to solve

Maybe targz can't be extracted, try to download zip packages.

I am also having problems the virtuemart installation. I am trying toinstall an old version which I have installed lots of time but I am now getting the following error msg;

"You do not have permission to access the requested module"

[jenkinhill]

dohalloran that was an old Joomla 1.5 error with Virtuemart 1.1 - these versions are no longer supported. But if you are interested in using vintage software then the fix was posted on http://rochcass.wordpress.com/2011/04/16/joomla-virtuemart-error-you-do-not-have-permission-to-access-the-requested-module-solution/

I cannot install.  My environment:  Centos 6.3
I created a new virtual server, then installed Joomla 2.5 no problem.  I then renamed htaccess.txt to htaccess

I then followed the easy instructions for VM 2.  But they are not easy.  From the mac I unzipped the first, and got two .tar.gz files.  Neither of them installs.
I then downloaded the "windows" file , extracted the first, and got 2 .zip files.  None of them works.

Please view my screen capture.

What am I doing wrong?

1. do not use .htaccess on localhost, especially if you have not also turned on SEF in Joomla. Only use SEF/.htaccess once a site is fully set up and tested.

2. You probably do not have high enough resources set for PHP.  eg these are the settings I use on a real server: http://forum.virtuemart.net/index.php?topic=102045.msg339125#msg339125

For localhost the timeout needs to be set higher as it will run slower.

I have increased the 4 values you suggested in php.ini as follows:
; Resource Limits ;
max_execution_time = 120
memory_limit = 128M
; File Uploads ;
upload_max_filesize = 32M
post_max_size = 32M

The MySQL Version is  5.1.67 and PHP is 5.3.3.

The issue is still there, however I thought I could place here a few lines of the web site error log where it complains of an error in line 322:

So your Joomla installation file does not have a favicon.ico and you have a couple of PHP warnings that Joomla is unable to open the file package. I guess that your server software is not compiles to unpack .tar.gz archives.  Try using the .zip version or unpack and install from a directory.

Thank you for your hints.
I should say that my centos installation DOES unpack the .tar.gz files, and that I already tried to upload various versions of VM from 2.09 to 2.16 and 2.18 both in .tar.gz and .zip formats and they all failed with just a cryptic error.
I then tried to install the .zip deom the /tmp directory as per your phoca hint (thanks) and I got this:
   •   JFTP: :mkdir: Bad response
   •   JFTP: :chmod: Bad response
   •   Component Install: Failed to create site directory: /var/www/vhosts/generac/components/com_virtuemart
   •   
This prompted me to think of linux permissions. So I logged in with a console ftp and tried to create a directory, a file, etc. and it all worked.  Here is a list -al of my installation:

I then started to think of doing a chmod 777, but then I decided that it did not make sense, because if FTP works, then JFTP should too.

I decided that what was missing is some permission for APACHE to write, and I found that , rightfully so, configuration.php has a permission of 644
So I decided to  try the following command to make the configuration file available to apache

chmod 664 configuration.php

I then tried to do the install from the /tmp directory and....  IT WORKED PERFECTLY.

To conclude this long explanation, I have discovered that:
1) the installation of VM must have write access to configuration.php    (NOT EXPLAINED ANYWHERE IN THE INSTALL INSTRUCTIONS)
2) Installing from the /tmp folder of your server WORKS !!!!
3) Attempting to do the "Easy Installation" by browsing your laptop folder, selecting a .zip or a .tar.gz  and clicking the UPLOAD AND INSTALL button  DOES NOT WORK even if the configuration.php is accessible   ( I would like to leave this to the VM developers )

Thank you for all the help.  Please flag this issue as SOLVED or at least PARTIALLY SOLVED.
