Good evening, when I'm trying to add an item to my shopping cart , give me the message:
"Strict Standards: Non-static method hikashop::loadUser() should not be called statically, assuming $this from incompatible context in /home/u695720947/public_html/plugins/hikashoppayment/bf_rbsbusinessgateway/bf_rbsbusinessgateway.php on line 62"
The message is displayed whether or not logged as evidence the attached images .
Thank you in advance for your help

Hi,

The notice message will be fix in the next release.
It is just a PHP notice, it is not seen as an error by PHP ; this kind of message can be display in a test/dev environment but should be hidden in a production mode.

If you want to fix that message, you can edit the plugin and replace in the line 62, the content By
