I’ve escalated this issue to our second-tier support team.
After reviewing the case, they recommended checking the server error logs to identify any potential issues. Could you please contact your hosting provider and request these logs?
They also noticed that the WP_MEMORY_LIMIT is currently set to 40M. Kindly increase it to 256M and let us know if that resolves the issue.
If the issue persists, further troubleshooting may require making changes to the site. For this, they’ve requested that you create a staging site where we can safely test those changes. Please share the staging site details once it’s ready.
You already have access to the FTP, there you can find the Logs from the hosting. We also put on a stating website on your end, but that works apparently. We really want to solve this issue, i think you already have all the information.
So please help us out here, because this issue is to big to give it more time.
