Hi there,
Thanks, I have able to login and check the backend of your site.
The site’s memory limit should be enough right now but the error still persists. I checked the error logs and there seems to be something on your site that is causing the issue. Would you mind testing for a plugin conflict. You can do this by deactivating all third party plugins, and seeing if the problem remains. If it’s fixed, you’ll know a plugin caused the problem, and you can narrow down which one by reactivating them one at a time.
Let us know how it goes!
