Hi Andy,
Thanks for reaching out.
There might be some different reasons behind your issue, I would like to suggest troubleshooting the following common issue to help us to recognize the reason.
1.Theme Related Issue
2.Plugin Conflict
3.Theme Update related issue
4.CSS/JS Customization
5.Disabling Cache
6.Increasing PHP Memory Limit
If you discover that an issue is coming from a custom code or 3rd party plugin, kindly consult with a developer or contact the plugin author. Please note that we do not provide support for custom codes and 3rd party plugins.
If none of the above helps and the issue persists, we need to investigate it thoroughly. I would suggest you upload the files to a server and please provide login credentials for your site in a secure note to examine it further, including:
– WordPress Site URL & Login URL
– WordPress Admin username/password
To create a secure note, click the key icon underneath any of your posts.
Thanks
