Hi, I am preparing to migrate the website at
adorablekateringcanapes.com.au/j4/
to Joomla 4. When I set error reporting to "Development" I see this error displayed:
Warning: implode(): Invalid arguments passed in /home/adorable/public_html/j4/templates/sparky_framework/index.php on line 33
Is this a problem I should address before attempting the migration? I have updated the template files, the installed extensions and of course core Joomla to 3.10.12. Looking at the error log file, the error has been occurring since I first built the website back in 2021.
You don't need to address this warning. After the Joomla upgrade to version 4, you will need to re-install the template anyway. This will overwrite the outdated files and warning will be fixed.
