Fatal error: Class 'ContentHelperRoute' not found in /home/dgeid2/public_html/modules/mod_articles_categories/tmpl/default_items.php on line 13

shows on all Hikashop pages after the Joomla 3.6.4 update. (latest Hikashop Business version and earlier) Any clues?

(No response from email support, so posting here.)

Hi,

Please understand that you send you message a Friday night in our support and then you posted you message in the forum like 4 hours later.
Knowing that we generally reply under 12 hours during the week and 24 hours during the week end (but it could be more ; for sure) ; you just have to wait and not duplicate your question using forum and email.

Now about your issue, you will see that the problem is related to the "mod_article_categories" module.
And that module in not an HikaShop one.
You might have configure that module to be displayed on HikaShop menus ; but it does not mean that HikaShop is the source of that problem.

Regards,
