I have a live Joomla site that is experiencing some errors. I believe it is because of an old version of Joomla and the new version of PHP after a server upgrade.
Your job will be to address the errors and/or perhaps upgrade to the newest version of Joomla. All the while maintaining the sites data. I understand if the site must go down briefly but it must be brief.
There is also an issue with an accordion menu going outside of the layout that must be fixed.
