 Hi, See the response from my hosting provider below. Posts are not
 publishing remaining as scheduled. This is an urgent issue. Sorry, I'm not
 a developer, just a frustrated user so can't tell you what's going on
 behind the scenes to cause this.

 Good morning,

 Thank you for your enquiry, and for your patience.

 We have been investigating this and can confirm that there is an issue
 regarding publishing new content in installations of WordPress that are
 using version 5.3 and above.

 This appears to have been caused by a recent update to the time/date code
 in the WordPress core files that has caused an issue with the recent
 change to British Summer Time.

 This is not a fault with the servers or hosting platform that you are
 using, and is something that WordPress appear to be aware of. We are
 currently unaware of any fix or resolution that WordPress may be reviewing
 or publishing and advise that you browse the support forums to see if
 there are any recent announcements:

 https://wordpress.org/support/forums/

 We have been testing a possible workaround that you may wish to try if you
 feel it is necessary:

 You can install a plugin from the WordPress repository that is called WP
 Downgrader and follow the instructions to reinstall WordPress 5.2.5 - this
 is the last known version of WordPress without the recent time code
 updates present that we know of.

 This is a decision that we will leave up to you, as we cannot speak for
 any negative effects this may have on plugin or theme compatibility, and
 we thoroughly recommend ensuring that you have a backup of all site and
 database content before you attempt to modify your WordPress installation.

 If you have any further problems or queries then please update this
 enquiry through the "Technical Support" section of your Control Panel, and
 we will be happy to help.
 Please rate our responses so that we may improve our service. Visit

 know how we've done.

 Kind Regards,
