Hello,
Thank you for contacting us and sorry for any inconvenience that might have been caused due to this issue.
We want to help you fix this issue as soon as possible. Please follow these steps:
- First, please install the Query Monitor plugin on your website. This plugin will help us identify any queries related to Rank Math that might be slowing down your site. Once you install it, please go to your dashboard and look for the Query Monitor icon on the top bar. Click on it and take a screenshot for us. You can use this tool to upload the screenshot and share the link with us.
- Second, please check the PHP values of your site by going to WordPress dashboard > Tools > Site Health > Info tab > Server. These values affect the performance of your site and they should be set according to the following recommendations:
PHP Memory Limit: 512M
Max input time: 150
PHP time limit: 120
PHP max input variables: 1000
If any of these values are lower than the recommended ones, please contact your hosting provider and ask them to increase them for you.
- Third, please go to WordPress Dashboard > Rank Math > General Settings > Analytics and reduce the number of days in the Analytics Database section. This will help you optimize the database size and speed up the loading time. You can choose to store 30 or 60 days of analytics data depending on your preference.
After you change the number of days, please save the settings and then click on the Delete Data button and then Update Data Manually. This will delete the old data and fetch the new data based on your settings.
