 * Hi downloaded your plugin and intalled, everything went fine until checkout, 
   clicked on pay with pesapal and it didn’t transfer to pesapal and gave this message:
   Problem: parameter_absent | Advice: > oauth_parameters_absent | oauth_consumer_key&
   oauth_signature_method&oauth_signature&oauth_timestamp&oauth_nonce
    [ps: I have
   entered the consumer and secret key in woocommerce admin]
 * I then realised I hadn’t put in the Ipn details on the pesapal site, but not 
   sure what it means by ipn listener url and what that should be. PLEASE Help
 * I also don’t understand what you mean by.
    ‘<?php do_action(‘plugin_name_hook’);?
   >’ is it name = your plugin name and by template do you mean in the theme file
   somewhere???
 * Ps I am not a coder but a designer, i use wp cos for the most part you only have
   to use a bit of css, so forgive my ignorance.

 * Am with “tukutane”…am getting the exact same error. I have used this plugin before
   with no issue on an older version of wp. I however tried it on the latest wp 
   version but cant seem to be successful.
 * Any help would be highly appreciated.
