Installation Problems

• I cannot install the component, com_versions.

Problem:  During installation, I receive the following error message

Error

• JFolder::create: Could not create directory
• Component Install: Failed to create directory.: "/mysite/components/com_versions"

Message

• Install Component Error

This is due to the fact that the installer cannot write to the Joomla directory shown in the error message, in this example, it's /mysite/components/com_versions.  Read here for more information regarding directory permissions.

Problem:  During installation, I receive the following error message

Error

• Warning! Failed to move file.

This is because the installer cannot write to /tmp.Read here for more information regarding directory permissions.

• How can I check if this is a permissions issue?

From the back-end of Joomla, choose "Help", then "System Info".  From there, check "Directory Permissions".  Be sure the following are writable:

administrator/components/    
administrator/language/*
components/
tmp/
language/*
plugins/
plugins/content/
plugins/editors-xtd/

• What if its not a permissions issue?
