Recently I updated my invoice plan version from 1.5.5 to 1.5.6
The problem happened when i tried to add new invoice, a massege appeared
It seems that the application stuck because of an error.
This is a copy of the log file contents
<?php defined('BASEPATH') OR exit('No direct script access allowed'); ?> ERROR - 2018-02-13 07:58:42 --> Severity: Warning --> unlink(./uploads/ABD-Webs300X67.png): No such file or directory /home/abdwebs/public_html/invoiceApp/application/modules/settings/controllers/Settings.php 173 ERROR - 2018-02-13 07:58:42 --> Could not find the language line "login_logo_removed" ERROR - 2018-02-13 07:58:42 --> Severity: Warning --> Cannot modify header information - headers already sent by (output started at /home/abdwebs/public_html/invoiceApp/vendor/codeigniter/framework/system/core/Exceptions.php:271) /home/abdwebs/public_html/invoiceApp/vendor/codeigniter/framework/system/helpers/url_helper.php 564
And this is a screenshot of my browser console
My hosting PHP Version is 7.0
Any suggestions ?!!
