Title: Error after migration. Last modified: May 16, 2018 --- # Error after migration. * Resolved [Izchel](https://wordpress.org/support/users/izysolutions/) * (@izysolutions) * [8 years ago](https://wordpress.org/support/topic/error-after-migration-5/) * Hi, I migrated a site in which this plugin was working perfectly. In the new hosting, it is throwing a 500 error in the Dashboard if the plugin is turned on. I found it might be due to the route… Debug printed: oldserver/public_html/ site/wp-content/uploads/woocommerce-pdf-invoices/attachments/.htaccess): failed to open stream: No such file or directory in newserver/public_html/site/wp-content/ plugins/woocommerce-pdf-invoices/includes/woocommerce-pdf-invoices.php on line 259 * Where can I update this? Any advice? * Many thanks Viewing 8 replies - 1 through 8 (of 8 total) * Plugin Contributor [Ewout](https://wordpress.org/support/users/pomegranate/) * (@pomegranate) * [8 years ago](https://wordpress.org/support/topic/error-after-migration-5/#post-10286102) * Hi! You have come to the wrong forum, I think you may be using this plugin: [https://wordpress.org/support/plugin/woocommerce-pdf-invoices](https://wordpress.org/support/plugin/woocommerce-pdf-invoices) * if that’s not it either, I would recommend checking the information in the WordPress plugins page, as this may hold more information about where to get support. * _[ [Signature deleted](https://wordpress.org/support/guidelines/#avoid-signatures)]_ * Thread Starter [Izchel](https://wordpress.org/support/users/izysolutions/) * (@izysolutions) * [8 years ago](https://wordpress.org/support/topic/error-after-migration-5/#post-10286454) * Sorry my bad. I was testing other plugins to see if it would fix it. * The plugin I have in the oldserver is WooCommerce PDF Invoices & Packing Slips but when I activate it in the new server, it throws a 500 error that only resolves when I change the folder’s name to let say _woocommerce-pdf-invoices-packing- slips. Then in the dashboard “The plugin woocommerce-pdf-invoices-packing-slips/ woocommerce-pdf-invoices-packingslips.php has been deactivated due to an error: Plugin file does not exist.” which makes sense. * Any advice?

Then we might see what is going on.

But if I check the error_log it shows this> * [16-May-2018 11:08:24 UTC] Aq_Resize.process() error: Image file does not exist( or is not an image): oldserver/public_html/site/wp-content/uploads/2017/11/Untitled- design16.png * Plugin Contributor [Ewout](https://wordpress.org/support/users/pomegranate/) * (@pomegranate) * [8 years ago](https://wordpress.org/support/topic/error-after-migration-5/#post-10290180) * [@izysolutions](https://wordpress.org/support/users/izysolutions/) to find the actual PHP error behind the 500 error, you can temporarily enable debug output in WordPress. See: [Example wp-config.php for Debugging](https://codex.wordpress.org/Debugging_in_WordPress#Example_wp-config.php_for_Debugging) * The `Aq_Resize` error is not from PDF Invoices & Packing Slips but appears to be from a plugin “Aqua Resizer” (it doesn’t look like a fatal error either so may be harmless). * Let us know what you find! * Thread Starter [Izchel](https://wordpress.org/support/users/izysolutions/) * (@izysolutions) * [8 years ago](https://wordpress.org/support/topic/error-after-migration-5/#post-10293166) * I got this: * [15-May-2018 14:20:54 UTC] PHP Notice: Undefined property: stdClass::$plugin in /newserver/public_html/site/wp-includes/class-wp-list-util.php on line 150 [ 15-May-2018 14:20:54 UTC] PHP Notice: Undefined property: stdClass::$plugin in/ newserver/public_html/site/wp-includes/class-wp-list-util.php on line 150 * Thread Starter [Izchel](https://wordpress.org/support/users/izysolutions/) * (@izysolutions) * [8 years ago](https://wordpress.org/support/topic/error-after-migration-5/#post-10293168) * the line is $this->output[ $key ] = $value->$field; on the public function pluck * Plugin Contributor [Ewout](https://wordpress.org/support/users/pomegranate/) * (@pomegranate) * [8 years ago](https://wordpress.org/support/topic/error-after-migration-5/#post-10293864) * Both of these are not fatal errors either, just notices. Neither are triggered by PDF invoices & Packing Slips either… I’m afraid we haven’t found the root cause yet!
