hi thanks for looking at this. I followed your tips and I changed line 166 into
public function setTemplate($template, $params = Array, $locale = NULL)
Unfortunatly now on that same page https://arte32.com/artisti I get this error and no other content is shown!
Parse error: syntax error, unexpected ',', expecting '(' in /home/artecomyur/www/modules/twovbrandsglossary/controllers/front/glossary.php on line 166
Therefore I had to reload the backup version of my glossary.php file (the one that gives me the errors that I mention on the top of my post)
