hello, just created a demo- and testsite with the fee version of RapidCart Pro 4. Exported the project to a local folder and uploaded its content to a subdomain ([https://hf22.bbzwww.ch](https://hf22.bbzwww.ch)). Now on the shop page _**shop-(hf22)**_ I get two lines of errors: ` **Deprecated** : array_uintersect(): Returning bool from comparison function is deprecated, return an integer less than, equal to, or greater than zero in **/srv/www/vhosts/bbzwww.ch/subdomains/hf22/httpdocs/rw_common/plugins/rapidcartpro/system/RCCatalog.php** on line **236** ` What does this mean and how can I correct this? ---

Looks like possibly a problem with the PHP version on your server. What version of PHP are you using? from the manual: On server side, **RapidCart Pro** requires **PHP 5.6+** and **TLS 1.2** support. It is also possible that your version of PHP might be too new - not sure what is the the latest version of PHP which will work with RCP. The manual is here: [https://tls.4gnd.com/rw/rapidcartpro/manual/#introduction](https://tls.4gnd.com/rw/rapidcartpro/manual/#introduction) This portion might be helpful: **Checklist and Debug** After first publishing, **RapidCart Pro** offers the chance to check if your web server satisfies RapidCart requirements. You can be redirected to checklist page pushing “Check your deployed page…” button, available from plugin’s inspector about panel. This page is also available simply adding `?checklist` at the end of your store’s URL (e.g. `http://www.domain.com/store/index.php?checklist`). If you encounter any issues with your **RapidCart Pro** store, enable _Debug Mode_ from _Customization Settings_ in _General_ section, republish your page and open a support ticket on [http://help.4gnd.com](http://help.4gnd.com/). Don’t forget to include your store URL in your request. ---

thanks David for your answer, my webhost is running PHP version 8 and so far the checklist looks fine (see screenshot). Only the PayPal option isn’t ok because there is no PayPal Business account existing yet. I will open a ticket in the 4gnd helpsystem then. Generally RapidCart is performing well to what my customer is expecting. I will have to show him this solution and discuss the next steps in a few days. ![Bildschirmfoto 2021-12-04 um 22.21.51](https://europe1.discourse-cdn.com/flex005/uploads/realmacsoftware1/original/3X/8/c/8c35eb22cc1ddde8041dba37ed3d10d6acd5978c.png) ---

Yes it’s probably best to open a support ticket. I don’t know if RCP 4 can use php 8 or not. 4gnd does have a beta for RCP 5 available, might be worth looking into as well. ---

David Debug Mode is set and the page is uploaded. But where can I open a ticket? The URL [help.4gnd.com](http://help.4gnd.com/) nowhere has the option to open a ticket and also on their website there is no link to any help or support not even some kind of “about us” or “comany info”! Anyway the webshop is located at [Shop-(hf22) | HistoryFacts Webshop](https://hf22.bbzwww.ch/page0/page0.php) and the error message still exists ☹ Hope this can soon be fixed. ---

[https://help.4gnd.com/general/#faq](https://help.4gnd.com/general/#faq) They’ve made it hard to find, but at the top of their general FAQ page it says: Drop an email to [help@4gnd.com](mailto:help@4gnd.com) You can also try tagging them here @rob @gibo ---

In the mean time you could try downgrading php to php7.4 or whichever is the last version of php7. ---

just set the PHP version to 7.1, the oldest possible version in my hosting settings. The error message still exists, switching back again to version 8 then. ---

after opening a ticket on Sunday evening I’ve got an email from 4gnd. The problem is fixed already in their test version. 😃 Until an update is posted I will turn off the PHP warnings on my webserver. This is done in the PHPini file. My testshop is now running on the RW plugin page. I will have to spend some time on getting a stacks page ready with RCP. ---
