General Joomla Installation Issues

E-mail Print PDF

JInstaller::install: Failed to copy file

Joomla Help Menu [Select System Info]This is a common message that usually results from file or directory permissions on the hosting environment. The easiest way to check if the problem is being caused by permission issues is to use Joomla's built-in "System Info" option in the Help menu.

When you select the "System Info" option, then you are presented with a range of information tabs about your website and the Joomla installation.

As shown in this screenshot one of the tabs you can choose is called “Directory Permissions’ - for you to be able to successfully install components, plug-ins and templates then all of these directories listed should show as “Writable”. If they don't (the directory permission show as “Unwritable”) you will need to change the permissions for your Joomla installation.

How do I change the permissions for my Joomla installation?

Joomla Directory PermissionsFirst up - changing permissions can be dangerous. If you don't really understand permissions and ownership get the technical support staff at your hosting service to fix the permissions for you. Specifically the webserver will need read and write access to the Joomla installation, it will also need ownership or membership of a group that owns the websites directories.

Changing permissions will depend on your website hosting setup.

  • If your host provides cPanel access you can use the “File Manager” to change the directory permissions.
  • If your host provides Shell access you can use chmod and chown to set the permissions to 755 and the group owner to the webserver's group
  • If your host has a custom control panel specific to them you may be best off opening a support ticket to get the problem resolved.

It's not my Permissions!

If your permissions are all showing as writable then the next most likely cause is that your Joomla installation is version 1.5.10 - a typical error in this case will look like this:

JInstaller::install: File
'/website/tmp/install_38bd786260b81/SomeComponent.install.php' does not exist.
Component Install: Could not copy PHP install file.

Joomla 1.5.10 had a slight change which causes this error to be thrown, it has been resolved in all subsequent versions. The simplest solution is to upgrade to a latter (and more secure) version of Joomla 1.5.

It's not my Permissions and it's not Joomla 1.5.10

Joomla_Global_Settings_FTP_OffIf you've gotten this far and it hasn't worked the final thing to check is your “Global Configuration” for “FTP Settings”. If you have FTP enable/disbaled, flip the FTP option (set it to the opposite setting) and try again.

 

In our experience with our software/templates and with Third Party products these steps have resolved 99% of installation issues via the Joomla Installer.

JCE - File Manger Introduction

E-mail Print PDF

JCE provides a range of extended options (via plug-ins) in the form of an extended “Image Manager” and an extended “File Manager”. The “File Manager” is the most basic and has many of the features of the “Image Manager” so it's an appropriate place to start.

The File Manager icon on the JCE toolbar looks like this: JCE File Manager Icon

JCE_FileManagerDialogEven though you are presented with an, at first, bewildering dialog box you should remember it's primary purpose is to allow you to place a link in your article to standard files that may be on your website ( like  ZIP, PDF's or other downloadable files ).

The dialog is based on the standard design and layout you would see if you were using Microsoft Word or Excel on a modern desktop computer to open/save a file, and as such, should be reasonably familiar.

 

Click on the screenshot to above and have a look at the dialog box and the annotations which show:

  1. Folders on your webserver (just Explorer or the Finder like on your computer)
  2. The files in the current folder (the one in bold is the currently selected one)
  3. Information about the selected file or folder is displayed in the 3rd column.
  4. The text that the link to the file is wrapped around.
  5. A range of tools for upload files to and working with folders and files on your webserver.

Using the File Manager

Linking a File

If you have some text selected when you click on the File Manager icon , the dialog box will use that text to fill out the “Text” field as shown in the screenshot above. When you click on a file name with text already in the “Text” field you will be presented with this dialog:

JCE File Manager - Replace Text?

As it states, if you click on the “Yes” it will replace the original with the file name which in most cases will not be what you want. Ideally the selected text that is displayed in the “Text” field should be appropriately descriptive as it will be used by Screen Readers and other assistive devices.

If you don't have some text selected the “Text” field will remain blank until you click on a file name - at that point the files name will be placed in the field. Ideally you should change this some descriptive text that will make sense to users of Screen Readers and other assistive devices.

Advanced File Links

Once a file link has been created you can use the “Advanced Link” button ( JCE Advanced Link toolbar button ) on the JCE toolbar to adjust a range of attributes including specifying a target, alternate title text Id, Style, Classes and a range of expert settings.

Unlinking a File

To unlink a file you will need to use the “Unlink” icon on the toolbar, it looks like this: JCE Unlink Toolbar Icon

Click on the link in the editor and the “Unlink” button will become active, click once on the button to remove the link completely.
