Hello,

We apologize for the issue you are facing with the Rank Math plugin. The error you provided indicates a type mismatch in the abs() function, which expects an integer or float but is receiving a string instead. This can happen due to various reasons, such as incorrect data being passed to the function.

To troubleshoot this issue, we recommend the following steps:
1. Update Rank Math: Ensure that you are using the latest version of the Rank Math plugin. Updates often include bug fixes and improvements that may resolve your issue.
2. Check for Plugin Conflicts: Deactivate other plugins temporarily to see if the error persists. If the error goes away, reactivate the plugins one by one to identify which one is causing the conflict.
3. Review Your Settings: Sometimes, specific settings or configurations can lead to unexpected behavior. Review your Rank Math settings to ensure everything is configured correctly.
4. Clear Cache: If you are using any caching plugins or server-side caching, clear all caches after making changes to ensure that you are testing the most recent version of your site.
If these steps do not resolve the issue, please reply to this ticket with any additional details or changes you’ve made, and a human agent from our support team will assist you further.

Thank you for bringing this to our attention, and we appreciate your patience as we work to resolve it!

Hi,

We are using the latest plugin (1.0.247) and cache has already been cleared a couple of times.
As far as we can see, there are no conflicts, settings see good (as newbies).

Please have one of your human experts double check for us.
We are planning to move to the ‘pro’ version very soon. And want to make sure the free is running smooth on our platform.

Regards,
Robert

Hello,

We have found the cause and are working on a fix, but before then, you may patch this by changing the file seo-by-rank-math/includes/modules/analytics/class-analytics-common.php lines 339 and 340

from:
```
$difference = isset( $item['difference'] ) ? abs( $item['difference'] ) : 0;
$is_negative = isset( $item['difference'] ) && abs( $item['difference'] ) !== $item['difference'];
```
to:
```
$difference = isset( $item['difference'] ) && 'n/a' !== $item['difference'] ? abs( $item['difference'] ) : 0;
$is_negative = isset( $item['difference'] ) && 'n/a' !== $item['difference'] && abs( $item['difference'] ) !== $item['difference'];
```
We apologize for any inconveniences that might have been caused as a result of this issue.

Please do not hesitate to let us know if you need our assistance with anything else.
