Some more info: website is built with Drupal 6.26 using Piwik Web analytics 6.x-2.2 module.
Please go to Settings > Websites and then remove from the list of "Global Search Keywords" the keywords parameter that your website uses in the URL. I should probably add FAQ for this.
Yes, that was it. Removed "q" keyword and now it's working as it was before. Thank you!
