Hello,
Thank you for your Help!
According to your suggestions, I find The conflict with Rank Math is Gutenberg.
Can you help me how can I solve this problem?
Thank you!
It seems like you are using the standalone Gutenberg plugin. Can you please switch to the in-built block editor of WP 5.0+? That will fix the issue immediately.
If you don’t want to switch, please wait for an update that will fix this issue.
We have fixed the issue internally and we will be releasing an update with a fix soon. Rest assured that you can turn off the Gutenberg plugin because apart from containing additional experimental features – it has nothing that the inbuilt Block editor of WP 5.0 doesn’t have.
Hope that helps and please do not hesitate to let us know if you need our assistance with anything else.
