I have a problem after upgrading to civicrm 5.4.1 from 4.7
When I confirm the record of a payment for a contribution the operation goes on forever and I have to exit the page although when I enter the contribution again the payment is registered.
When I look into the ajax requests with the Chrome DevTools I see that when the "record a new payment" popup is loaded it loads this script from the server (extract):
<span id='totalAmount'> <select class="eight crm-select2 eight crm-form-select required" name="currency" id="currency">↵ <option value="EUR" selected="selected">EUR (€)</option> </select> <input size="6" maxlength="14" name="total_amount" type="text" value="1.00" id="total_amount" class="eight six crm-form-text required" /> </span> <span class="status">Balance Owed: € 1,00</span>
Why is the value in total_amount 1.00 and the value showed in the Balance Owed 1,00?
When I confirm and register the payment the loading of the page goes on forever and when I look into the DevTools I see that this happens as the ajax request answers with an error:
Sorry, due to an error, we are unable to fulfill your request at the moment. You may want to contact your administrator or service provider with more details about what action you were performing when this occurred. amount is not a valid amount: 1.00
Can anyone help with some ideas?
