Hello,

Thank you for your patience.

To determine the root cause of the issue, please activate Rank Math and install the plugin Query Monitor to the affected website and look for slow queries related to Rank Math.

Once done, take a screenshot of the query and share it with us so we can identify the cause of the issue. You can use this tool to upload the image and add the generated link here.

Meanwhile, please set/ensure the following recommended PHP values on your site for troubleshooting (if not yet):

PHP Memory Limit: 512M
Max input time: 150
PHP time limit: 120
PHP max input variables: 1000

Let us know how this goes.

Hello,

The PHP memory limits should have to be increased from your server. You can check the PHP values of your site by heading over to your WordPress dashboard > Tools > Site Health > Info tab > Server. If they are set too low on your site, please ask your hosting provider to upgrade the values.

If the issue persists, then we might need to take a closer look at the settings. 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:

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):

Let us know how it goes. Looking forward to helping you.

Thank you.
