Thanks for contacting us. A gateway timeout error is usually related to the server's limited resources. I'd suggest checking with your hosting provider about this.
My site is fine, no issues reported, the only issues is using menu sync. It normally takes a few minutes to come up, the php timeout is 5 minutes, the gateway timeout occurs in 2minutes 30 seconds. I have 12 additional languages besides English.
I will need to closely examine your website. Therefore, I will require temporary access (WP-Admin and FTP) to a test site where the problem has been replicated, if possible. This will enable me to provide better assistance and determine if any configurations need to be modified.
Please note that it is important to have a backup for security purposes and to prevent any potential data loss. You can use the UpdraftPlus plugin (https://wordpress.org/plugins/updraftplus/) to fulfill your backup requirements.
Your upcoming reply will be treated with confidentiality and will only be visible to you and me.
✙ To resolve the issue, I may need your consent to deactivate and reactivate plugins and the theme, as well as make configuration changes on the site if necessary. This emphasizes the significance of having a backup.
