Hello,
I am trying to use Pesapal with Woocommerce via this plugin (wordpress.org/plugins/pesapal-for-woocommerce/)

but I get this error when I try activating the plugin:

Fatal error: Cannot redeclare class OAuthSignatureMethod_HMAC_SHA1 in /home/innovise/public_html/tujuane/wp-content/plugins/pesapal-for-woocommerce/libs/OAuth.php on line 134

How can I fix this?

System:
Woocommerce ver.2.1.9

Hi p_njo,

You have another plugin that's including the OAuth file. You need to find out which plugin it is and comment out the code that does the inclusion. Else comment out our OAuth. If you do so make sure you never uninstall the other plugin that include the OAuth :-)

My greatest guess, you have a twitter plugin :-)

I do have a twitter plugin :)

I need to use it so only option is to comment out pesapal OAuth. How do I do that?

Thanks so much for the fast response

Hello,

Open this file "wp-content/plugins/pesapal-for-woocommerce/libs/OAuth.php"


Add a wrapper around the class in question. WHat this does is ignore the code withing the IF statement if you've already loaded the class

if(!class_exists( $classname ) ) {
// Maintain our code
}


eg..


if(!class_exists("OAuthSignatureMethod_HMAC_SHA1") ) {
class OAuthSignatureMethod_HMAC_SHA1 extends OAuthSignatureMethod {
function get_name() {
return "HMAC-SHA1";
}

public function build_signature($request, $consumer, $token) {
$base_string = $request->get_signature_base_string();
$request->base_string = $base_string;

$key_parts = array(
$consumer->secret,
($token) ? $token->secret : ""
);

$key_parts = OAuthUtil::urlencode_rfc3986($key_parts);
$key = implode('&', $key_parts);

return base64_encode(hash_hmac('sha1', $base_string, $key, true));
}
}

}
