Title: Error after migrating website Last modified: August 24, 2016 --- # Error after migrating website * Resolved [Jonas Xander](https://wordpress.org/support/users/john-alexander/) * (@john-alexander) * [11 years, 2 months ago](https://wordpress.org/support/topic/error-after-migrating-website/) * I have this error showing up on my header: * `Warning: array_filter() expects parameter 1 to be array, boolean given in /home/ englishaffair/public_html/wp-content/plugins/woocommerce/includes/class-wc-cart. php on line 212` * I suspect it might because I had an item added to cart before I backuped up the site and migrated it to another domain. Or it could just be nonsense, and the error is something else. * This is really annoying.

[http://www.yoursite.com/cart](http://www.yoursite.com/cart) * It’ll say your cart is empty. just click return to shop button. that annoying warning msg will disappear. * That’s how I fixed it. Hope it helps * Thanks * [kdanley42](https://wordpress.org/support/users/kdanley42/) * (@kdanley42) * [11 years, 1 month ago](https://wordpress.org/support/topic/error-after-migrating-website/#post-6043402) * Thank you very much for your response. That actually didn’t work for me. I was only getting the warnings when I was in the backend, but not while logged in. When I did what you suggested (while logged in), it actually threw more warnings and the web page didn’t even show anymore. When I logged out of the backend and logged back in, the warnings disappeared. I don’t understand the reason, but i’ll take it. * [kdanley42](https://wordpress.org/support/users/kdanley42/) * (@kdanley42) * [11 years, 1 month ago](https://wordpress.org/support/topic/error-after-migrating-website/#post-6043403) * I’m sorry – I meant I was only seeing it on the front end while I was logged into the backend. * [saintmonkey](https://wordpress.org/support/users/saintmonkey/) * (@saintmonkey) * [11 years, 1 month ago](https://wordpress.org/support/topic/error-after-migrating-website/#post-6043405) * Yep the typing domain/cart also brought up more errors for me, but as suggested logging out and back in removed them … * very odd I wasted a whole day on this lol thanks very much for the advice 🙂 * [Dhanuka Nuwan](https://wordpress.org/support/users/dhanukanuwan123/) * (@dhanukanuwan123) * [11 years, 1 month ago](https://wordpress.org/support/topic/error-after-migrating-website/#post-6043406) * try adding a product to the cart and then empty it. * [saintmonkey](https://wordpress.org/support/users/saintmonkey/) * (@saintmonkey) * [11 years, 1 month ago](https://wordpress.org/support/topic/error-after-migrating-website/#post-6043407) * works fine * [WebThePlanet](https://wordpress.org/support/users/webtheplanet/) * (@webtheplanet) * [11 years ago](https://wordpress.org/support/topic/error-after-migrating-website/#post-6043409) * I encountered this problem when I cloned over a stage site I built for a client to their url. There was items still in the cart que. This also caused the media manager to stop working as well. * Whatever the issue, this was the fastest way to fix the issue. * 1 – Backup Your Site! 2 – Install [https://wordpress.org/plugins/wp-optimize/](https://wordpress.org/plugins/wp-optimize/)( WP Optimize) and activate it. 3 – Run WP Optimize (don’t forget to uncheck “Delete Revisions” if you want to keep them. Mostly you want to delete the transients. * Hope this helps someone. I fixed the site in 2 minutes. * [Nate Finch](https://wordpress.org/support/users/finchps/) * (@finchps) * [11 years ago](https://wordpress.org/support/topic/error-after-migrating-website/#post-6043410) * I tried Dhanuka Nuwan’s fix, and it worked. I added an item to the cart and removed it and the error message went away. * Thanks Dhanuka! You’re the man! * [Dhanuka Nuwan](https://wordpress.org/support/users/dhanukanuwan123/) * (@dhanukanuwan123) * [11 years ago](https://wordpress.org/support/topic/error-after-migrating-website/#post-6043411) * glad to help you 🙂 Viewing 15 replies - 1 through 15 (of 17 total) 1 [2](https://wordpress.org/support/topic/error-after-migrating-website/page/2/?output_format=md) [→](https://wordpress.org/support/topic/error-after-migrating-website/page/2/?output_format=md) The topic ‘Error after migrating website’ is closed to new replies. * ![](https://ps.w.org/woocommerce/assets/icon.svg?rev=3234504) * [WooCommerce](https://wordpress.org/plugins/woocommerce/) * [Frequently Asked Questions](https://wordpress.org/plugins/woocommerce/#faq) * [Support Threads](https://wordpress.org/support/plugin/woocommerce/) * [Active Topics](https://wordpress.org/support/plugin/woocommerce/active/) * [Unresolved Topics](https://wordpress.org/support/plugin/woocommerce/unresolved/) * [Reviews](https://wordpress.org/support/plugin/woocommerce/reviews/) * 17 replies * 8 participants * Last reply from: [rightmost](https://wordpress.org/support/users/rightmost/) * Last activity: [10 years, 9 months ago](https://wordpress.org/support/topic/error-after-migrating-website/page/2/#post-6043456) * Status: resolved
