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.
Could you please share the error message so we can check?
You can also follow this guide to enable debugging in WordPress
https://wordpress.org/support/article/debugging-in-wordpress/ or you can get in touch with your web host, and they will help you locate the log file.
Having an error log will help us determine what is causing the issue with the Instant Indexing.
Looking forward to helping you.
Hello,
I have updated the sensitive data as requested. Can you please check further?
Thank you.
Whenever I try to make changes on the site:
When I try to update a post, I get the message: “Updating failed.”
When I try to update a page, I also get the message: “Updating failed.”
When I try to delete a product, I am redirected to:
“There has been a critical error on this website. Please check your site admin email inbox for instructions. If you continue to have problems, please try the support forums. Learn more about troubleshooting WordPress.”
Hello,
We require more details from the information you shared. Since its a critical error, an error log would be helpful for us to determine the issue.

Sorry, I had a plugin installed that restricted backend access for other areas.
I have disabled it.
Hello,
The debug.log file where site errors are logged is too large on your site, about 648MB. So we are unable to access it.
You should reduce its size. You can refer to this thread: https://wordpress.stackexchange.com/questions/345638/problem-with-size-of-debug-log-file
We look forward to helping you.
Thank you.
I deleted the old log. Now the new information can be seen.
Hello,
We checked your website but were not able to replicate the issue while publishing, updating, or deleting any post on your site.
If you’re still facing the issue on your website, please share a screencast with us by using a tool like https://loom.com so that we can check this further for you.
Looking forward to helping you.
Thank you.
Yes, it seems that at this moment there is no more error.
The only change in the site is the deletion of the debug.log file
Thank you for your involvement.
