I have figured that this was happening because only Papyal express checkout was enable. So when I turned of checkout option from product and cart page, Place order button was appearing at checkout page.

Now the issue is that my default currency is QAR, for that I have added QAR in paypal currecny list using this code.

add_filter('woocommerce_currency_symbol', 'add_qar_currency_symbol', 10, 2);  
 
function add_qar_currency_symbol( $currency_symbol, $currency ) {  
  switch( $currency ) {  
  case 'QAR': $currency_symbol = 'QAR'; break;  
  }  
 return $currency_symbol;  
}

add_filter( 'woocommerce_paypal_supported_currencies', 'add_qar_paypal_valid_currency' );       

function add_qar_paypal_valid_currency( $currencies ) {    
   array_push ( $currencies , 'QAR' );  
   return $currencies;    
}

And coverting usd to qar using this function

add_filter('woocommerce_paypal_args', 'convert_qar_to_usd', 11 );  
function get_currency($from, $to){
  $from = "USD";
  $to = "QAR"; 
		
  // create curl resource 
  $ch = curl_init(); 
 
  // set url 
  curl_setopt($ch, CURLOPT_URL, "https://free.currencyconverterapi.com/api/v5/convert?q={$from}_{$to}&compact=ultra"); 
 
  //return the transfer as a string 
  curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); 
 
  // $output contains the output string 
  $output = curl_exec($ch);
  // close curl resource to free up system resources 
  curl_close($ch); 
  $data = explode(':', $output);
  $data = explode(" ", $data[1]);
  $amnt = round($data[0], 2);
  return $amnt;
}

function convert_qar_to_usd($paypal_args){
    if ( $paypal_args['currency_code'] == 'QAR'){  
	$convert_rate = get_currency(); //Set converting rate
	$paypal_args['currency_code'] = 'USD'; //change AED to USD  
    $i = 1;  
        while (isset($paypal_args['amount_' . $i])) {  
            $paypal_args['amount_' . $i] = round( $paypal_args['amount_' . $i] / $convert_rate, 2);
            ++$i;  
        }  
		if ( $paypal_args['shipping_1'] > 0 ) {
			$paypal_args['shipping_1'] = round( $paypal_args['shipping_1'] / $convert_rate, 2);
		}
		if ( $paypal_args['discount_amount_cart'] > 0 ) {
			$paypal_args['discount_amount_cart'] = round( $paypal_args['discount_amount_cart'] / $convert_rate, 2);
		}
		if ( $paypal_args['tax_cart'] > 0 ) {
  			$paypal_args['tax_cart'] = round( $paypal_args['tax_cart'] / $convert_rate, 2);
		}
			
	}
return $paypal_args;  
} 

But its still showing currency problem. Please look into the problem.

Hi, the error was removed when I changed the currency to USD, but now no button is appearing on either cart page, checkout page.

@johndcoy I am still waiting for the help.

Hi, I have already switched to default theme and only WooCommerce and PayPal Checkout plugin are active but the problem is still there.

On product page & cart page “PayPal” Button appears but on checkout page “PayPal” button doesn’t even appear.

On clicking PayPal button on product and cart page, this error appears “PayPal error (10605): An error (10605) occurred while processing your PayPal payment. Please contact the store owner for assistance.”

On checkout page, apparently no error appears but on checking console too many errors appears.

For testing I have set the scenario on this website:
https://armapparels.com

and the pages are :
https://armapparels.com/cart/
https://armapparels.com/checkout/

Its firing too many errors, which are as follows:

Hi,
After seeing the error log file following error was causing 500 error:

PHP Fatal error: Call to undefined function Dompdf\mb_internal_encoding() in /home/xxxx/public_html/wp-content/plugins/wp-invoice-pdf/lib/third-party/dompdf/src/Dompdf.php

After a quick google I have fixed the problem after enabling php_mbstring extension.

Thanks for the help.

@mariakravchenko how much memory that WP Invoice requires to generate a PDF file?w

@mariakravchenko

Disabling all other plugins and changing theme didn’t worked aswell.

Hi,

Previously it was working fine, now it is showing HTTP 500 Error.

Tried removing logo and it’s not working aswell.
