In this Joomla Tutorials, i will be using Site Maintenance In Joomla 1.7. For maintaining a Joomla 1.7 website, you have to first login through the administrative panel of Joomla by simply entering the yoursite.com/administrator in your browser.
Enter the username, password and leave the Language to Default, click on Login.
After logging in to the backend, a control panel page opens.
The Control Panel provides access to many default Joomla! functions and features. From the Control Panel, you can create and manage articles and categories. Other features available in the Control Panel are the media, menu, language, and user managers.
In the top menu, locate the link – Site. Click on Site, from the drop down menu that appears click – Maintenance as shown in Image 1.
The maintenance menu item that has been added to Joomla 1.7 collates all of the general site maintenance features that are in Joomla. These include: Global Check-in, Clear Cache, and Purge Expired Cache.
Joomla 1.7 allows Administrators to “check-in” or unlock items currently “locked” or in-use by other users.
When the administrator accesses an article or module in the Joomla site, the access to that particular part of Joomla is blocked to any other user. Sometimes it is necessary to clear this blocked access, as a users’ session may have expired or the article or module that was being edited didn’t have access to the item closed correctly. The Global Check-in will clear all access restrictions due to another user accessing the content item and allow others to gain access.
NOTE: Ensure that no one is busy editing any items before performing a global check-in. When a Global Check-in is done, all items are checked in, including those currently being edited.
When the system cache plugin is turned ON, the website will start caching all the pages of the website while being tested or viewed.
There are times when it is required to clear the cache in order to see changes made to the content of the website. Do that by navigating to Site -> Clear Cache.
This tool will delete all Cache files from the cache folders – including current ones – from your web server. As admin functions are cached too, some cache folders might appear as if they were not cleaned because they get recreated before cache content is rescanned after this action.
Cache files are temporary files that are created to improve the performance of the Joomla site. If you have made significant changes to your web site, your cache files may be out of date. To avoid problems caused by out of date cache files, simply delete all of the cache files.
Purge Expired Cache:
The cache within Joomla has an expiry time. This time is setup in the configuration of the site and the caching plugins. When these cache files expire, Joomla will create new cache files. From time to time it is required to purge the expired cache as it continues taking up disk space. Do this by navigating to Site -> Purge Expired Cache.
This tool will purge all expired cache files from the cache folders. This process checks each cache file individually.
– Purge Expired Cache is recommended to be run on a regular basis; however this will require more system resources because each file is checked.
– Clean Cache option is quicker, however all cache files will be deleted.
– If you receive a PHP timeout error or warning during the process, it is ok to start this process again.
