Last some days, we got many questions about problem during update Joomla! 3.x to 3.7. So, today I would like to make step by step how to process update your Joomla! system (from Joomla! 3.5) to Joomla! 3.7 without any problems for your website.
I/ Prepare to update to Joomla! 3.7
As my exp to update some websites for our customers to Joomla! 3.7 before, you must to do some tasks before run update:
1/ Backup your all website (you can make backup via auto backup in your hosting, or any backup service).
2/ If you’re using other templates (different with default Joomla! templates), ask your template provider about compatible problem with Joomla! 3.7, if they have patch update, process update for your template.
* If you’re EngineTemplates customers, feel free to process update, we tested wih all Free Joomla! templates from us, and make full support for Joomla! 3.7.
II/ Start to update your Joomla! 3.x to Joomla! 3.7
After finished update, if you have alert with DB record problem, don’t worry, just go to Admin > Extensions > Manage > Database, click to button “Fix” to correct it.
If you see warning with custom fields (new features in Joomla!) and need to active plugins as screenshot below
Go to Plugin Manager, search for keyword ‘system – fields’ and enable it.
* Joomla! 3.7 has some changes, at least HTML for com_content, so HTML override folder in template must to update in order to use new features such as article Custom Fields. That’s why I told you about template compatible.
