Error: 404 Not Found

The extension is still working ok but still I thought it would be good to record this notice.

PHP Deprecated: parse_url(): Passing null to parameter #1 ($url) of type string is deprecated in /var/www/vhosts/xyz/web/sites/all/modules/civicrm_extensions/nz.co.fuzion.cssinline/packages/cssin/src/CSSIN.php on line 257

Eileen: Now that we're on CiviCRM 5.10.3 we're hitting errors on max execution time of 300 in this extension. I added a .htaccess setting it to 800 in the directory.

Can anything be done? What are best practices?

I see you have no LICENSE file for this project. The default is proprietary.

I would suggest released the code under the GPLv3 or AGPLv3 license so that others are encouraged to contribute changes back to your project.

Thanks! : )

I'm using PHP 8.3, Nginx and Smarty4.
Don't know if this is only occurring with this specifications, but I also found that the modification of "template_dir" is not totally consistent with the Smarty class implementation.
Got an improved version that works for my setup.
I don't know if this also works for earlier PHP version and/or Smarty.

  static $configured = FALSE;
  if ($configured) return;
  $configured = TRUE;

  $template = CRM_Core_Smarty::singleton();

  $extRoot = dirname( __FILE__ ) . DIRECTORY_SEPARATOR;
  $extDir = $extRoot . 'templates';

  if ( is_array( $template->template_dir ) ) {
        $template->addTemplateDir($extDir);
  } else {
        $currentDirs = array($extDir, $template->getTemplateDir());
        $template->setTemplateDir($currentDirs);
  }

  $include_path = $extRoot . PATH_SEPARATOR . get_include_path( );
  set_include_path( $include_path );
}

I don't know if it is an issue but I recently upgrade CiviCRM to 4.7.10 and when Send Scheduled Mailings cron job runs I get this error:

Fatal error: require_once(): Failed opening required 'CSSIN.php'

I workaround this by patching line104 of cssinline.php from

require_once 'CSSIN.php';

to

require_once 'packages/cssin/src/CSSIN.php';
