Hi,
I will be happy to assist you with the issue you are facing.
It seems like a conflict with one of the plugins or the theme you are using. To determine that, can you please follow this troubleshooting guide?

Only the site admin would know and your users won’t be affected by this troubleshooting.
Personally, I think there is some issue with your theme but please follow the above steps to know fo sure what’s causing this.
That didn’t solve my problem
If that doesn’t work, we might need to take a closer look at the settings. Please include your WP logins in the designated Sensitive Data section.
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):

We really look forward to helping you.
