Updating from joomla 3 to 4
First read the official instructions of this mini migration by clicking here. Then these are my template related instructions, if you don't want to lose your template parameter settings, and template modifications:
- You have joomla 3.x, now backup your site e.g. with Akeeba Backup
- Save the old template, especially your user.css if you have one in the css folder
- Update joomla to joomla 3.10, clear the cache if you have, and test the site in incognito mode of your browser
- Update the extensions, and test the site again
- Set Protostar to the default template
- Update joomla 3 to joomla 4, and test the site, now you should see the Cassiopeia template.
- Remove the a4joomla-best folder in an FTP client, or delete the folders and files of the template from the admin area if possible. Thus we keep the old template settings in the database, and we remove just the old template files and folders.
- Install a4joomla-best4! Now you will have two template styles with the same name: a4joomla-best. Try to set them to default, and test the site to see, which one contains your old template parameter settings. Keep that one, and you can delete the other template style.
- Update other extensions, test the site, etc.
Some CSS classes should be replaced if you hide some of your modules on mobile with css classes in the "Module class suffix". You can find the new css classes for hiding modules here. You can hide modules on different display sizes: xs=extra small, sm=small, md=middle, lg=large, xl=extra large, xxl=the largest.
After template installation and choosing it to the default template, click on the template's name in the template manager to set the parameters.
The template uses a 12-column grid, so the Layout/Right column width, and the Layout/Left column width are the number of columns in the 12 column grid. You may have to play with these settings. Always check how the site looks when you decrease the browser window size, because the template is responsive, and the look of the site changes with the browser (or display) size.
The social and search icons will be displayed only if you type some URL for their parameters. You have to set up a search page, and put its URL to the search page parameter to have a search icon. To make a search page, create a new hidden menu, that has no published module, then create a new search menu item, save it, and copy its alias to the end of the site URL to see the search page.
The main sections of the template parameters:
- background and logo
- fullscreen header
- social icons
- module positions
If you use an image logo, I suggest to resize it in a graphic editor e.g. to have a height of 70px.
Top menu (dropdown menu) settings:
In position-1 you can setup a dropdown menu, just remove everything from the "Menu class suffix" and "Module class suffix" of this module in the module manager! Also set the "Show submenu items" to "Yes"!
Topbar horizontal menu (dropdown menu)
In position-13 you can also setup a horizontal menu, just remove everything from the "Menu class suffix" and "Module class suffix" of this module in the module manager! There are also settings of the topbar in the template parameters.
Side menu style
If you want a side menu that looks like the menu on the left, set the "Module class suffix" to _menu and remove everything from the "Menu class suffix"!
You can set a title for these module position in the template parameters, a background image, the color of the background, text, heading, and links. You can place this module position above or below the joomla content area. The module widths can be set by setting the Bootstrap size in the module settings. The sum of the Bootstrap sizes of the modules must be 12, as the template has a 12 column grid.
Module positions that are not shown in the picture below are: position-6 (right sidebar), user4...user10, inner1 (just above the joomla articles), inner2 (just below the joomla articles), slideshow (for a 3rd party slideshow module).
This template is responsive, so it adapts to the size of the mobile device. You can also see this on a desktop computer when you decrease the size of your browser. But it's worth hiding some of the modules on mobiles, because the order of the content of the website corresponds to the order of that in the source code. For this purpose you can use some css classes for the modules in the "Module class suffix". You can find the css classes for hiding modules here. You can hide modules on different display sizes: xs=extra small, sm=small, md=middle, lg=large, xl=extra large, xxl=the largest.
You can put your own CSS code into the css/user.css file that you have to create if you need it.
You need to upload 3 favicon files into the images folder of the template: favicon.ico, joomla-favicon.svg, and joomla-favicon-pinned.svg. First create the favicon.ico file and a safari-pinned-tab.svg file from your png or jpg here: https://realfavicongenerator.net/ . Then convert your png or jpg file to svg here: https://convertio.co/png-svg/ . Then create a favicon.svg file from your svg here: https://realfavicongenerator.net/svg-favicon/ . Now rename the safari-pinned-tab.svg to joomla-favicon-pinned.svg, and the favicon.svg to joomla-favicon.svg, and upload them together with the favicon.ico file into the images folder of the template!
