HTTP ERROR 500 when trying to access URL for Suite CRM

Since the morning of 8th March 2019 I have been unable to log in to Suite CRM. I get an HTTP ERROR 500 whenever I click on the saved bookmark rather than it taking me to the log in screen. I have tried to add a screenshot of this error but when I click the Add file button nothing happens

The URL i am using is http://78.46.206.226/recommended_hotels_crm/index.php?action=Login&module=Users&login_module=Accounts&login_action=DetailView&login_record=dbb7e79e-6020-32e6-0182-5a13ea602487

Can you try checking your web server logs? An 500 error is a crash in your web server. It can have a million different causes, and your logs should point you in the correct direction.
