Error in newer version php

-- url of the page with the problem -- : nieuw.megiq.com/
-- HikaShop version -- : 4.2.2
-- Joomla version -- : 3.9.15
-- PHP version -- : 7.3.14
-- Browser(s) name and version -- : Microsoft Edge
-- Error-message(debug-mod must be tuned on) -- : Deprecated: strripos(): Non-string needles will be interpreted as strings in the future. Use an explicit chr() call to preserve the current behavior in /home/megiq038/nieuw/administrator/components/com_hikashop/helpers/helper.php on line 3010

After changing tp php 7.3.14 i get the error message:
Deprecated: strripos(): Non-string needles will be interpreted as strings in the future. Use an explicit chr() call to preserve the current behavior in /home/megiq038/nieuw/administrator/components/com_hikashop/helpers/helper.php on line 3010

I get it only in Microsoft Edge.

How can I solve this?

You mean the complete Hikashop business? The zip or the tar.zip version?
