Hello,
Thank you for contacting Rank Math and bringing your concern to our attention. I’m sorry for any inconvenience this issue may have caused you.
The is_cart() function is defined in the WooCommerce plugin and before using it we check if the plugin is active on the site.
Assuming you are using the latest version of all the plugins, WordPress, and the themes (please update if not yet), it would seem like a conflict with one of the plugins or the theme you are using.
1. Could you deactivate all other plugins and reactivate Rank Math alone? It seems like some other plugin conflicts with Rank Math. If you are still facing the issue please share the screencast using loom.com so that we can investigate further.
2. If Rank Math activates without any issue then start activating other plugins one by one and try to find which plugin causes the problem.
3.To determine that you can follow this troubleshooting guide also:
https://rankmath.com/kb/check-plugin-conflicts/
Only the site admin would know and your users won’t be affected by this troubleshooting.
If the issue is still not resolved, please let us know.
We really look forward to helping you.
Thank you.
Hi,
Mine is a multisite network with WP ultimo.
I do not have woocommerce active on this subsite where the error happens.
I havent tried it on sites with woocommerce active.
However for this subsite, deactivating all but rankmath still reproduces the issue.
Please advise.
Hello,
In this case, we might need to inspect your admin dashboard ourselves.
Please edit the first post on this ticket and include your WordPress & FTP logins in the designated Sensitive Data section.
Please do take a complete backup of your website before sharing the information with us.
It is completely secure and only our support staff has access to that section. If you want, you can use the below plugin to generate a temporary login URL to your website and share that with us instead:
https://wordpress.org/plugins/temporary-login-without-password/
You can use the above plugin in conjunction with the WP Security Audit Log to monitor what changes our staff might make on your website (if any):

We really look forward to helping you.
