It is recommended to be enabled only for modules that contain static content.If you’re reading this post then probably the following has happened (or is currently happening) to you: – You disable a module (or change a template, or disable/enable/update any extension).– You go to your website and check if the module is no longer there. – You go back to the administrator’s backend on Joomla, you double check if the module is disabled, and it turns out to be really disabled.But you enable it and disable it again, just in case….In Joomla 3.4 a new, based on the PDO, database driver for My SQL, was added (rapidly becoming the new de facto driver for My SQL database connections).However an incomplete check for the existence of the PDO driver was implemented for some users who didn't have the driver installed with PHP.There you can also control the time that a cached content should be remained, before it is considered expired and therefore replaced with a new one.
We receive a call every other day from new clients telling us that one of their Joomla articles is not updating: They can see the updates in the backend, but the frontend does not show the updates.I am changing/updating content in the joomla backend and saving. Joomla provides the following caching levels: It stores a full copy of the rendered page. It is also disabled by default and can be accessed in the Global configuration - System.But any change I do will not appear in the front-end instantly. It is controlled by a system plugin : Plugins Manager - System Cache plugin, and it is disabled by default. It provides 2 caching ways: Conservative and Progressive cache. Keep in mind too that when you install a template, it does not auto matically activate it.You may be making changes to a template that is not activiated.
