Information about the Update to 3.6.3/en Since the Security change in com_joomlaupdate with 3.6.2, it has been difficult to update to the last version. Notice too that html page you have included inherits css styles from Joomla! template. If you need to access tables within the same database as your Joomla! installation then you can simply use the JFactory->getDbo method.
For this reason, if possible we recommend that you install a new copy of Joomla with all the demo content in place with our quickstart package. You will have to rewrite every old plugin syntax instance. We are very sorry for the inconvenience it will bring you. On the other hand it will bring you more possibilities, better security and more flexibility.
