Ok so they changed it for me via FTP. My site worked fine then, but after changing rename back to original and activated plugin it broke site again.
i lodged a ticket at PayFast and this is the nmessage i got:
The PayFast WooCommerce plugin is developed and managed by WooCommerce, we are, therefore, unable to make any changes to the plugin as we do not own it. Please can you continue to reach out to WooCommerce as they will be able to offer support for their plugin.
Thanks i asked my hosting company to do it for me.
Thanks for the reply, but my problem is I can’t login to my site, it’s just like a white screen..
