The error "0 Cannot use positional argument after named argument" typically occurs due to syntax incompatibilities between the PHP version you're using and the code in your VirtueMart or Joomla installation. Here’s a concise way to solve this issue:
Update Extensions: Ensure all your Joomla extensions, including VirtueMart and Themler, are up-to-date. Newer versions may have fixed compatibility issues with PHP 8.0.
Check PHP Compatibility:
If updates don’t resolve the issue, downgrade to PHP 7.4, which is more compatible with older Joomla and VirtueMart versions.
Change PHP version through your hosting control panel or by contacting your hosting provider.
Fix Code Manually:
If you’re comfortable editing code, locate the file and line number mentioned in the error message.
Rearrange the function arguments to avoid mixing positional and named arguments. Example:
php
function example($arg1, $arg2, $namedArg = 'default') {
// Your code here
}
example('value1', 'value2', namedArg: 'custom');
Consult Documentation:
Check the official Joomla and VirtueMart documentation or forums for any specific instructions regarding PHP 8.0 compatibility.
Contact Support:
If you’re unable to resolve the issue, contact Joomla, VirtueMart, or Themler support for assistance.
By updating your extensions, possibly downgrading PHP, or manually fixing the code, you should be able to resolve the error and access your VirtueMart category page.
